5 Most Curious Loops and Cycles and Re-Sets

Time travel has long been a captivating concept in storytelling, allowing creators to bend the rules of causality and explore the intricate web of cause and effect.

In the realm of film and television, there's a plethora of narratives that delve into the complexities of temporal mechanics, weaving together plots filled with curious loops, cycles and resets that leave audiences both fascinated and bewildered.

The following is taken from Destination Time Travel by Steve Nallon and Dick Fiddy.

1. Shadow Play (1961)

In a Kafkaesque ordeal, a prisoner faces trial and subsequent execution for a murder charge in a public court. However, the nightmare doesn't end there; following the execution, the entire sequence replays, with a peculiar twist—the familiar faces reappear, but their roles have been reshuffled. Now, the judge, lawyers, and jury assume different character roles in the eerie repetition. This surreal narrative unfolds in Season 2, Episode 26 of Twilight Zone, originally aired on May 5, 1961. The episode, written by Charles Beaumont and inspired by his 1956 short story Träumerei, offers a chilling exploration of cyclical justice and existential dread.


2. Run Lola Run (1998)

A heart-racing experimental thriller, crafted by the talented Tom Tykwer, follows our protagonist Lola as she races against the clock. With a mere 20 minutes to deliver a bag of money to her boyfriend before his perilous fate at the hands of his criminal boss, Lola's journey unfolds in a relentless pursuit against time. Despite her frantic efforts, she falls short, only to find herself thrust back to the beginning as time resets, granting her another chance. However, each iteration of events presents a different series of circumstances, all culminating in inevitable disaster before time resets once more. Featuring a captivating performance by Franka Potente as Lola, the film delivers exhilarating entertainment. Enhanced by a dynamic soundtrack that mirrors Lola's relentless running, this cinematic experience is a pulse-pounding exploration of fate and second chances.


3. Heaven Sent (Doctor Who 2015)

The Doctor finds himself ensnared in a castle, relentlessly pursued by The Veil, a sinister presence. His only hope of escape lies in confronting the truths of his existence. Within the castle, the very space and structure are in a perpetual state of rearrangement, adding to the Doctor's disorientation. Despite the passage of time—whether measured in days, years or even the lifespan of stars—the Doctor's day eventually resets, trapping him in an endless cycle.

The purpose of the Doctor's confinement remains shrouded in mystery. Is he there to confront his inner demons, to mourn the loss of Clara, or to undergo a trial of resilience and self-reflection? While the concept of hell is mentioned, the theological parallels in Heaven Sent lean more towards the Catholic notion of purgatory—a realm of penance rather than punishment.

In the original Doctor Who series, the Doctor often functioned as a Travelling Angel, arriving to resolve conflicts and set things right. However, the rebooted series delves deeper into the Doctor's psyche, portraying a character burdened with guilt and existential angst. Steven Moffat's Heaven Sent serves as a culmination of this character arc, offering a profound exploration of the Doctor's nature and inner turmoil.


4. Children of the Stones (1977)

The crucial distinction between a time loop and what we might term a 'time cycle' lies in the characters' awareness of their situation. In a time cycle, characters are oblivious to the fact that they are trapped within a repetitive world, and for some, the possibility of breaking free exists. In the concluding episode of Children of the Stones, titled Full Circle and written by Jeremy Burnham and Trevor Ray, this distinction is highlighted. The village depicted in the story is revealed to be ensnared in a recurring time cycle, resetting to its initial state—the arrival of Hendrick—at the story's conclusion. However, the main protagonists manage to escape the village, completely unaware that they have been part of a perpetual time loop.


5. Triangle (2009)

A chilling slasher film unfolds aboard a boat, punctuated by a series of self-inflicted deaths. While it may not follow the traditional time loop narrative like Groundhog Day, this film is expertly crafted and offers a refreshing twist on the theme of cyclical time. Triangle, written and directed by Christopher Smith, boasts meticulous plotting and skilful direction, making it a captivating deviation from the typical circle of time storyline.


Time travel film and television offer a rich tapestry of narratives that explore the most curious loops, cycles and resets imaginable. Whether it's unraveling the mysteries of the past, contemplating the ramifications of altering history or confronting the inevitability of fate, these stories captivate our imaginations and challenge our perceptions of time itself.

As we continue to ponder the enigma of temporal mechanics, one thing remains certain—our fascination with time travel will endure for generations to come.
