"It Happened One Night” director (5)
I believe the answer is:
capra
'it happened one night director' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for capra that I've seen before include "One of the 22 who directed" , "Frank --, US film director" , "Italian-American film director of It's a Wonderful Life, d.1991" .)
