Yeah, its the one with Bob Geldoff, who actually does a tremendous acting job, especially since he:

(1) Never acted before, nor since, I believe.
(2) Had to act out his emotions and feelings without saying one word of expositional dialogue, which many trained actors simply can't do.
(3) Actually hated Pink Floyd's music. Yet Parker was able to get him for the movie with his ambitions for the movie itself, since Waters apparently had a spectacular failure of a screen test. In fact, I wonder if thats a reason why he has low regards for the movie, but thats just conspiracy talking.
