The Best Time Loop Movies: How Do You Make Repetition Unique?

Writing Time Loops

Time loop movies have been popular since their classic, most famous origin, Groundhog Day. This style has risen in popularity particularly within the last decade due to the inventive depictions and increasingly clever escapes and excitement within the time loop monotony.

When every day feels the same, how do we make them count? The best time loop movies, such as Groundhog Day, Edge of Tomorrow, and Palm Springs, all highlight the human frustration of feeling stuck. They challenge us to consider the meaning of life and our place within it. 

Built on the foundation of characters who find themselves trapped in a time loop, repeating the same day over and over, time loop movies present a complicated challenge: how do you make repetition unique? 

So we’ve compiled some key elements of writing a time loop movie. In an increasingly crowded genre, what are the key pitfalls and tropes to avoid? But also, what are the essential elements that make up a time loop movie in the first place?

The Key Elements of a Time Loop Movie:

1. Write Compelling Protagonists

Time loop movies depend on their characters. When each day is the same, the development of the film comes from the changing of the characters. Let’s look at some examples.

Phil Connors in Groundhog Day

Groundhog Day is the blueprint for time loop movies and its protagonist contributes greatly to the film’s persevering success.

  • Phil Connors, portrayed by Bill Murray, begins the story as a jaded, unsympathetic journalist covering Groundhog Day in Punxsutawney, Pennsylvania.
  • He is condescending towards the town and its people and shows a lack of enthusiasm for his job and the event. This gives his character room to improve.

Connors’s character does grow as he relives the same day. He stops indulging in one night stands, copious amounts of food, crime, and manipulation granted by the knowledge he gains from living the day so many times.

His improvement keeps viewers hooked; they, of course, want to see him break the time loop. But more importantly, they want to see him become someone different by the end of the loop. What would be the lesson of reliving the same day if Connors solved the loop and did not change?  

Give your characters space to improve, and do so by assigning specific flaws to your characters. Connors’s flaws aren’t automatically there; they had to be chosen by the screenwriters. Select the ways in which your character will be flawed.

It is also important to decide on the balance between watching the main character grow and keeping the viewer entertained. The character cannot take too long to change. The audience has to sense this change is happening throughout, no matter how gradual it might feel.

William Cage in Edge of Tomorrow

Edge of Tomorrow - Official Trailer 1 [HD]

In Edge of Tomorrow, Major William Cage, played by Tom Cruise, is inexperienced in combat and lives life prioritizing his own well being. He is at his core a self-preservationist.

  • When General Brigham requires Cage to join the soldiers landing on Normandy Beach for Operation Downfall, Cage attempts to blackmail Brigham in order to avoid doing so.
  • He is not concerned with fighting for the greater good, or even representing those who do; he simply wants to survive. 

This mindset is challenged as Cage enters the time loop. He is the only one with a shot at saving humanity from its demise and must become someone mentally and physically strong enough to kill the invasive alien race.

This setup allows for Cage’s character to grow. Despite the movie focusing on the same day, each day feels different because Cage is different. His improving combat skills, his developing relationship with Rita, and his growing understanding of the alien race and the problem at hand allow for each looped day to feel like a new one.  

Nyles and Sarah in Palm Springs

Palm Springs - Trailer (Official) • A Hulu Original Film

Both protagonists in Palm Springs have unresolved issues at the beginning of the film.

  • Nyles, played by Andy Samberg, has been trapped in a loop so long he doesn’t even remember his own job. He has resorted to accepting his never-ending fate within the time loop, until meeting Sarah, played by Cristin Milioti
  • Nyles has given up on the idea of escaping the loop and yielded himself to living within it forever. When Sarah finds a possible way to escape, Nyles ultimately decides to go with her because he no longer wishes to be in the loop without her. He has finally come to care about someone enough to try and change his fate. 

Throughout the film, Sarah is ridden with guilt over having an affair with her sister’s husband-to-be. Though overcoming this remorse is not the key to escaping the time loop, it is necessary for Sarah’s character to come to terms with her actions in order to find the determination and a way out of the loop. 

Nyles and Sarah are good examples of writing flawed characters that viewers continue to care about and stay invested in. Their growing relationship, their confrontation with each of their personal problems, and their ultimate growth by the end of the movie hooks viewers and makes them engaged with the story.

Make your characters imperfect. Make them weak, ignorant, or selfish, and then use the time loop to give them the time and the means to improve. Not only will this grant you an intricate, compelling character, but it also will capture viewers’ attention and keep them invested in the story in a fundamental way.

2. Create a Clever Setting for the Loop

Palm Springs Time Loop Movie

While the characters primarily carry time loop movies, the plot and conflict still drive the story. The day that is being looped needs to be open enough to allow the characters to do many different things within the confines of the story. So the setting is vital in this regard.

In Palm Springs

Palm Springs has the perfect balance of possibility and structure.

  • Set in Palm Springs, California on the day of a wedding, Nyles and Sarah spend much of the day doing a variety of things, from performing a choreographed dance in a bar to flying a plane.
  • The evening consists of a wedding reception and the various ways the two are able to incite chaos. It also fosters heartfelt speeches and tender moments between the characters. 

The breakup between morning and evening allows for the movie to have a break from repetition. The wedding is ample opportunity for lots of character interaction. It’s used in comedic ways, such as Nyles trying to steal the bride away during the first dance. Or it’s used in emotional ways, such as Sarah giving a profound toast. 

The wedding setting also allows for characters such as Roy to enter the story. Roy’s vengeful pursuit of Nyles, a result of Nyles getting him stuck in the time loop as well, adds suspense and danger to what is otherwise a benign story. 

In Edge of Tomorrow

Edge of Tomorrow uses geography to drive the plot forward.

  • Though the day is repeating itself, Cage must make his way up the beach and ultimately find and kill the Omega in order to save the world.
  • Cage makes it a little further each day, surviving the beach and then the deserted field, making his way to London, and eventually arriving in Paris. 

This physical progress not only allows the days within the loop to differ but also creates stakes.

  • Cage’s progress does not carry over to the next day; if he makes it all the way past the beach and dies, he will have to repeat that success again.
  • This becomes increasingly tense after learning that the Omega is in Paris, since Cage has to successfully complete a series of difficult tasks and manoeuvres in order to reach it alive. 
  • We can barely handle watching the repetitions at a certain point as much as Cage can handle experiencing them. This is a clever way of creating tangible stakes.

Ultimately, you need to use your setting as a tool. A good backdrop will act as a catalyst for the story, and should give you opportunities to explore different experiences within the same day of a time loop

3. Find a Satisfying Solution

A crucial part of good time loop movies is a satisfying solution. How do the characters break the time loop

Each movie approaches this in a different way. 

  • The loop in Groundhog Day is broken when Connors finds happiness in life through his love for Rita. The loop is dependent on Connors’ emotional growth. 
  • In Edge of Tomorrow, the loop is broken by a blood transfusion. The loop in this movie, however, is not the central conflict–Cage desperately tries to keep the time loop from ending so that he can successfully kill the Omega and the alien race. 
  • In Palm Springs, the loop is broken through an explosion. This is explained through quantum physics, which Sarah begins to study after she resolves to escape the loop. 

What Do Each of These Movies Do Right?

Each loop is unique and makes sense within the context of the movie. The end of the loop in Groundhog Day depends on Connors’ happiness because that is the crux of the film. It wouldn’t make sense for anything else to be the solution to his problem.

The Edge of Tomorrow time loop is connected with the alien’s biology.

  • This makes sense, particularly after scenes in which Cage and Rita discuss the alien biology that causes this to happen.
  • Using blood as the key to the time loop also adds tension, since receiving a blood transfusion would break the loop and Cage would lose the war.

While the time loop in Palm Springs is solved by using quantum physics, it is ultimately driven by Sarah’s resolve.

  • Sarah and Nyles accept by the end of the movie that they are willing to die to escape the time loop because they would rather die trying than exist in the time loop without one another.
  • They have moved past their reluctant stasis and are willing to face their lives that they have been kept from.  

In conclusion, the solution to breaking the time loop should be unique and specific to the characters, story and setting. Don’t manufacture a time loop break based on previous time loop movies. Instead, connect to the core distinctiveness of your story.

Don’ts of Time Loop Movies

DON’T Steal Ideas

One of the crucial don’ts of time loop movies is unoriginality. If you choose to copy an existing time loop movie, the audience will know; you will be repeating repetition. 

Paying homage to a classic or referencing other time loop movies is acceptable. But being original with your ideas is critical with this particular style of movie. Make sure the origin of your story is not the desire to create a time loop movie but that instead, you are using the time loop device to enhance your story.

DON’T Overuse Confidence and Control

Many time loop movies include a sequence in which the characters make every decision right and don’t miss a step. For example, they save a person from walking into the street just in time or catch something that normally would have hit them in the head.

This perfection is briefly interesting, as viewers get to watch the characters use the knowledge and reflex gained from experience to perfectly execute the day. The reality is that most viewers would love to experience that feeling, the moment where they can have that much control and make the right decision with no doubt.

Don’t use this satisfaction of confidence as a crutch, though. There is a line that if you cross it will produce an effect in which the audience is bored. While it is satisfying to watch characters exert full control over their situation, it isn’t interesting to watch repeated success; viewers want to see characters struggle and then triumph.

DON’T Rely on the Stereotypes

There are also a few clichés and tropes to avoid when writing your script for a time loop movie:

Minimize or utilize the main characters’ bewilderment about the time loop.

  • Audiences have seen main characters struggle to come to terms with a time loop in nearly every time loop movie.
  • Cut down on this reaction, or use it to your advantage, but ultimately avoid forcing viewers to watch the main characters live the same day over and over in disbelief.

Death and suicide are commonly used in time loop movies since the characters no longer have the consequence of staying dead.

  • Don’t overwhelm your viewer with this, though.
  • Use the opportunity of death to add comedy or tension to your script, but don’t just fill it with unnecessary deaths simply because you can.

Don’t jump the shark. Time loops are already extreme and nearly unbelievable.

  • In order to have some credibility with your audience, you have to make the character’s arc convincing.
  • If you don’t make each mistake and discovery believable to the character, then the movie becomes ridiculous and lacks any kind of truth.

DON’T Balk from Big Themes

Finally, don’t shy away from the metaphysical, the astrophysical, the geophysical. Time loop movies, although often comedic, touch on serious and complicated themes.

  • The ending of Palm Springs depends entirely on Sarah’s understanding of quantum physics and general relativity.
  • Edge of Tomorrow deals with biology, as the time loop is rooted in how the Alpha alien blood affects Cage.
  • Groundhog Day meanwhile, whilst seemingly rooted in a relatively simplistic romantic narrative, still conveys some profound commentary on seizing the day, acting selflessly and connecting to a higher purpose.

All three movies touch on one’s existence in the universe; how do we interact with the world? How does human interaction shape us, and what does it mean to have those interactions erased every day? Don’t be afraid to explore these big concepts in your script.

To Conclude: Embracing Creativity

Writing time loop movies requires significant creativity. With the structure of the story being focused on repetition, you must make your characters and what they do unique and engaging. 

Your main character should not have life all figured out. A protagonist who is perfect at the beginning of a movie would have little growing to do in a time loop. A flawed character, however, is confronted with their imperfections and desires when taken out of their day-to-day life.  

Furthermore, choosing the right setting for the time loop is crucial. This day, the surroundings and its people will be on screen over and over again. Make sure it is something viewers are willing to watch repeatedly, and something that you as a screenwriter can utilize to create many engaging scenes. 

Finally, make your solution stand out. With time loop movies rising in popularity for both audiences and screenwriters, it is key that your time loop differs from the others. What makes your movie, your time loop, worth watching?
