In this Godather II screen-test clip, Sam Fuller‘s Hyman Roth is a bit too affable, too menschy…no scent of menace or perversity. He could be the manager of a minor-league baseball team. I’ve watched two or three big-name actors run through lines and try stuff out on movie sets prior to shooting, and I was reminded each time that most readings aren’t anything to write home about.

In other words, even the best actors aren’t instant “get it right the first time” geniuses. Like anyone else they need to find their way through trial and error and refinement, etc.
