I’m sorry but every time I listen to the brief conversation between James Cagney‘s “C.R. MacNamara” (inspired by then-Defense Secretary Robert McNamara?) and the painter guy, I bust out chuckling. It happens between 2:12 and 2:19.

“We had to go with Cagney because Cagney was the whole picture. He really had the rhythm, and that was very good. It was not funny, but the speed was funny…the general idea was, let’s make the fastest picture in the world…and yeah, we did not wait, for once, for the big laughs. — One Two Three director-writer Billy Wilder talking to Cameron Crowe.
