Bad actor: The Judge
I enjoyed this movie immensely -- especially, Jimmy Stewart's character. But, the character of the judge did not seem right. At first I thought they had chosen a really bad actor to play the judge because he seemed to be reading his lines. But, then I concluded that they had probably chosen a real judge to play the judge, in the mistaken belief that the real judge's quirky, humorous, folksy self would translate well to the screen -- but it did not. I was close. According to IMDb, the part of the judge was played by the real attorney who represented the Army during the Army-McCarthy hearings. They should have hired a real actor.
Did anyone catch Jimmy Stewart's "I'm only a humble country lawyer" remark? I believe this remark was later stolen -- and made famous -- by Senator Sam Ervin, the Chairperson of the Watergate Hearings.
