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.
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.
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.
