The Wrong Man (1956)

Hitchcock says at the top that "every word" of the story is true... which, no. But it is based on the an actual family-man who gets picked up by the cops on suspicion of being guilty of several hold-ups in the area. It was difficult to see this through the eyes of the time: I was frustrated at Manny (the accused) for being so passive and not demanding a lawyer. He was so eager to help that he didn't see the danger in doing so. 

That aside, the story is an interesting one, though it does go on too long.
