Stories from the set

The film's title is borrowed from Alexander Pope's poem "Eloisa to Abelard" (1714). Charlie Kaufman also used this same poem when creating the earlier project "Being John Malkovich" (1999).

Nicolas Cage showed considerable interest in the role of Joel, but in the end it went to Jim Carrey.

The company specializing in memory erasure is called "Lacuna Inc." The word Lacuna has Latin origins and means a gap or omission. It is also worth noting that the term "lacunar infarct" refers to an infarct in which a small part of the brain becomes responsible for performing a specific function (in particular, memory).

The idea for the plot came to Michel Gondry after a conversation with the artist Pierre Bismuth, who suggested the following: Early in the morning you open your mailbox and receive the following message: "The one you knew has just erased you from their memory..."

All the scenes in the train were shot in real existing carriages of a moving train. It was decided not to resort to sets.

The opening credits do not begin until the 18th minute of the film.

The surname of the nurse Mary never appears in the final credits, but if you watch the film carefully, you can notice a frame in which it can be recognized. That surname is Svevo. It was chosen not at all by chance, in honor of the Italian writer Italo Svevo (1861-1928), who was actively interested in the works of Sigmund Freud and believed that he had managed to enter into correspondence with the philosopher.

In the original version of the film there was a scene of the last night of Joel and his ex-girlfriend Naomi (Ellen Pompeo), but it never made it into the final version of the film.

The actors were allowed to improvise during filming, which they gladly took advantage of.

The computer used in the procedures is called the Amstrad PPC (portable personal computer). This model was considered quite popular in the early 90s.
