Trivia: Bob Geldof hates this film. He is quoted as saying "I hated it! I was embarrassed. I didn't know what I was getting into... I thought my acting was terrible. The script was ridiculous. And I hate Pink Floyd. As you may recall I was a punk rocker, so if you want to say something just keep it to three minutes..." He had to be physically restrained by director Alan Parker when he tried to get up and leave during the preview screening of the film at Cannes. In his autobiography "Is That It?" he trashes the film at length, labelling the script as puerile nonsense, and is particularly scathing about the political stance it appears to take. He had a miserable time on the set (reportedly, so did everyone else) and now refuses to even talk about the film or his experiences making it.
Trivia: At a few points, a World War II film is on the television in Pink's hotel room. The film is "The Dam Busters," (1954) and audio clips from the film can also be heard on the album "The Wall."
Trivia: When Pink is in the bathroom (the last time we see it), dressed as the Hammer leader, he is reading some poems. Before he reads "Stop, I wanna go home.", he's reading parts of "The Final Cut", an album of Pink Floyd which came after of "The Wall".
Trivia: Pink is in the bathroom stall crying, and reading from his songbook. He reads, "Do you remember me? How we used to be? Do you thing we should be closer?" That is from the song, "Your Possible Pasts" off of "The Final Cut" album, which was released a year after the movie.
Answer: It's a portrait of Bob Dylan by Andy Warhol.
