Triangle

Memento is a neo-noir psychological thriller about a man with short-term memory loss using notes and tattoos to hunt for his wife's murderer. Like Triangle, it uses a non-linear narrative to disorient and engage the audience, making it a compelling watch for fans of puzzle-like stories.

Looper fuses action with time travel, featuring hitmen whose targets are sent from the future. While more action-packed, it shares Triangle's themes of causality and the moral complexities of meeting one's past or future self.

A low-budget yet exceptionally complex film, Primer explores the unexpected consequences of a homemade time machine. The film's intricate plot and the way it handles the physics and paradoxes of time travel will resonate with those who enjoyed the challenging narrative of Triangle.

A Spanish-language thriller with a cult following, Timecrimes features an accidental time traveler who finds himself entangled in a series of disturbing temporal loops. Similar to Triangle, the movie employs a tight, cerebral plot that will captivate fans of thought-provoking science fiction.

Christopher Nolan's Inception is a stylish exploration of the subconscious mind through dream manipulation. While it doesn't involve time loops, it offers a similar level of narrative complexity and a reality-questioning story that will appeal to fans of Triangle.
