The Conversation (1974)

Continuity mistake: Gene Hackman returns a second cookie to Harrison Ford's dish that he hadn't taken - or perhaps it's the same cookie he picked up and returned a moment earlier. Either way, the cookie had suddenly appeared in Hackman's hands going from one shot to another. (00:30:35)

Trivia: The dream sequence in which Harry tries to talk to Ann was originally meant to take place in real life (within the film, that is). The production didn't have time to finish the scene and the fog effects looked too phony. But rather than scrap the scene entirely, editor Walter Murch came up with the idea to include the footage as a dream.

Trivia: The final repetition of the line "He'd kill us if he had the chance" had its inflection changed because preview audiences became preoccupied with questions over whether Harry had misinterpreted the couple's conversation or if they were deliberately being misleading (or both). The ambiguity was initially intended, but appeared to work a little too well and distracted the audience from appreciating the rest of the ending, so this delivery of the line was made more definitive.

Trivia: The main character's name "Harry Caul" was the result of a typo; his name was meant to be "Harry Call," but Francis Ford Coppola ended up liking the mistaken name even better.

Stan: What a stupid conversation.

Harry Caul: I'm not afraid of death, but I am afraid of murder.

Mark: Does it bother you?
Ann: What?
Mark: Walking around in circles.

Question: What's the name of the piano solo music which can be heard throughout the movie? Since the movie has no soundtrack, can someone please give me its name and the place where it can be found?
