He was a very funny little man. He would squat on a ladder like a frog, watching you go through a funny routine, and he’d laugh so much he’d fall off.

By the tenth or twelfth take you realised that you were far from your original interpretation — you were playing pure Lubitsch.
-David Niven, about director Ernst Lubitsch
