Roger Waters wrote the screenplay for Alan Parker's 1982 film, which helps explain why it so flawlessly captures the hallucinatory, politically bracing underpinnings of Pink Floyd's landmark "The Wall." The melding is so perfect that after one viewing of the film, it becomes nearly impossible to listen to the album without playing the cinematic imagery along in your head. You probably can't give illustrator Gerald Scarfe enough credit as well for his contributions to a film that's one memorable moment after another. This is the meat-grinding, hammer-marching, nipple-slicing embodiment of a certain type of rock-n-roll ethos, imitated by many but successfully replicated by few.
