The title contain 6 "a"s for the 6 different actors playing Dali. However, more were originally announced: both Alain Chabat and Pierre Niney left the project as they felt they were not bringing anything to the role.
Writer/director Quentin Dupieux didn't want to make a proper biopic of the painter, as he felt it would make no sense. Dalí's greatest masterpiece according to Dupieux was his extravagant personality, so he attempted to make a non-movie about that.
The soundtrack is composed and performed by one half of famous French Touch duo Daft Punk: Thomas Bangalter. Only one instrument is used: an ancient zither. Bangalter had previously made a cameo in Dupieux's Reality.
According to the director, the humor in the movie is mostly inspired by British comedy troupe The Monty Python, as the never-ending hallway scene makes clear.
The movie was shot in six weeks in November and December of 2022, in Saint-Cloud near Paris, in the South of France and in Spain, where a house on the Costa Brava was made to look like Dalí's house in Portlligat.
