555-0134 is the most popular phone number in movie history. Marla Singer’s phone number in 'Fight Club' is the same as Teddy’s number in the movie “Memento.”
It is also the same as the Hong Kong Restaurant’s phone number in “Harriet The Spy,” Eddie Alden’s phone number in the movie “Someone Like You,” and the number for a mental institution in an episode of the show “Millennium.”
