The St. Valentine's Day Massacre (1967)

Factual error: The narrator near the beginning says Al Capone was born in Italy. He was actually born in Brooklyn NY.

Reporter: Y'know some are sayin' that it really was the cops who shot those men.
Bugs Moran: You must be new to this town, mister. Only Al Capone kills like that.

Capone: Wanna know something Jack? I like a guy who can use his head for something beside a hatrack.
