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.

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.
