There are over 1,500 movies in the IMDb that feature time travel, some going into the future and others, like The Butterfly Effect, jumping into the past. One of the movies recommended by viewers of The Butterfly Effect that involves time travel into the past is Somewhere in Time (1980), in which a playwright uses self-hypnosis to jump back to 1912 in order to find a famous stage actress with whom he has become obsessed. Another recommended movie is Jacob's Ladder (1990), in which a Vietnam vet awakens in his future but is haunted by flashbacks into his past. The House in the Square (1951) tells the story of a man who is transported by a lightning strike back to 1784 London. In the Back to the Future movies, Marty McFly jumps back and forth between past, present, and future. In the first Back to the Future (1985), he jumps back 30 years in time and almost prevents his own parents from meeting, falling in love, and getting married. In Back to the Future Part II (1989), Marty jumps to the future and learns that he must go back to 1955 to rectify the damage he caused on the first visit. Finally in Back to the Future Part III (1990), Marty jumps all the way back to the 1885 Old West in order to save his friend Doc Brown.

Wells' classic of all classic time-travel movies, The Time Machine (1960) and its remake, The Time Machine (2002), a scientist jumps into the far future to find that the human race has divided into two races—the gentle Eloi and the cannibalistic Morlocks. A classic and highly regarded time travel movie is Twelve Monkeys (1995), in which the world is infected with a virus, and a convict has to travel back through time in order to obtain a pure sample of this virus. A lesser known but nonetheless interesting time travel movie is Retroactive (1997), in which a traveling woman unwillingly gets involved in a time-travel experiment and ends up reliving the previous hours during which she has to prevent a murder and several other disasters. Like in The Butterfly Effect, this movie deals with someone doing flashbacks, in which small changes in the past produce largely different outcomes in the future. There is Donnie Darko (2001), in which a mentally-disturbed teenager is given the chance to change events in recent history, and Eternal Sunshine of the Spotless Mind (2004), which features the erasure of memories and the re-creating of a romantic relationship. Finally, Edge of Tomorrow features a soldier who dies on the battlefield, and then finds himself back one day earlier, alive and well. He discovers that he returns to that same moment each and every time when he dies, and learns to make use this to win the war.
