Roger Corman
If you don't remember Roger Corman's lines from The Silence of the Lambs, don't worry, because he didn't have any! The director is seen first in the film as a portrait on the back wall of an office. Later on, he appears as the FBI director. It's important to note though that Corman didn't actually direct The Silence of the Lambs, but was very close with Jonathan Demme, who really directed it. The two started their careers together and had supported each other ever since.
