Everything, Everywhere, All At Once (2022)

In one reality, you need to pay your taxes and explain to the IRS why karaoke machines count as a vital part of your business expenses. In another, you’re a famous chef, actress, or martial arts master who never married the love of their life but lived out their most successful and highest timeline. Which reality would you choose? Evelyn Wang is tempted by the possibilities of the infinite multiverse as she goes head-to-head with the “dark” alternate version of her daughter, Alpha Joy, who threatens the very existence of it. She also juggles her strained relationship with her husband Waymond who she comes to appreciate as she meets different parallel versions of him, realizing that in every reality, he operates with the kindness and empathy that may very well save the world. Everything, Everywhere, All At Once is a beautiful film about the power of love and its ability to transcend the barriers of time and space. 

Interstellar (2014)

Joseph Cooper is a former NASA pilot who is forced to abandon his children Cooper and Murph to travel through space and save humanity from extinction in the search for habitable planets on the Endurance spacecraft. Aside from Amelia’s love for physicist Wolf Edmunds which causes her to travel across the galaxy in hopes of seeing him and the planet he may occupy which could be habitable, there is is a brief romance in the film between Murph and Getty, a NASA medical doctor, as well as some possible romantic tension between Amelia and Cooper. Yet the true “love story” throughout the film remains the strong familial bond between Murph and her father Cooper. Cooper is essentially able to travel through different points throughout their history in a four-dimensional tesseract to communicate to Murph the messages needed to save the world, defying time and space to do so. As Amelia eloquently puts it, “Love is the one thing we’re capable of perceiving that transcends dimensions of time and space.”

Timer (2009)

Unbeknownst to her, her stepsister Steph tried to introduce her to a man who is actually her true soulmate, Dan, but they have a missed connection when Oona decided not to show up because she is being romanced by another man, and Steph actually begins a flirtation with Dan instead. In a series of serendipitous and chaotic circumstances, Oona struggles to release her expectations of meeting “the one,” only to find her soulmate at the last minute. Talk about good timing. 

Sliding Doors (1998)

This 1998 film starring Gwyneth Paltrow splits into two different timelines. In one timeline, Helen Quilley misses her train in the London Underground after she drops an earring in the elevator and a man picks it up. In another, she boards the train and sits beside the fellow traveler, James, who picked up her earring, and they make a connection. She later arrives home to catch her boyfriend cheating with his ex-girlfriend. In the latter timeline, she leaves her boyfriend and falls in love with James. However, in both timelines, horrific circumstances ensue that threaten her life, and only one of them lead to a somewhat happy ending. Sliding Doors is an epic alternate timeline movie about love and missed connections, how infinite possibilities and life-course trajectories can branch off one another, and how even the most tumultuous detours can lead to happy endings. It illustrates the domino effect of how even the slightest changes in our choices can lead to a complete “timeline shift” in our destinies.
