So, I was watching the Godfather Epic last night and the scenes with Woltz brought up a question in my mind. When Tom first meets him, he explains that he's got one client and his client would be grateful if he gave Johnny the part in the movie. Woltz loses his mind and says that isn't going to happen.

Next scene is at Woltz's house. He asks Tom why he didn't tell him worked for Corleone. Said he thought he was just a hustler that Johnny sent. But then at dinner he tells Tom he knows all about the band leader story.

My question is, if Woltz knew about the band leader, why would he assume that Tom was just some hustler that Johnny sent. Why wouldn't he assume that this singer/actor with a well know connection to the mafia wouldn't use that connection to get the part?
