When browsing the IMDB page for Clint Eastwood's adaptation of the hit musical "Jersey Boys," you might have found yourself saying, "Who?" But, as evidenced by the performances by stage stars John Lloyd Young, Vincent Piazza, Erich Bergen, and Michael Lomenda, Eastwood's decision to cast actors straight from the show's Broadway and touring productions was a good one.

"It seemed logical to use people that had this tremendous amount of experience playing it," Eastwood told MTV News. "Name actors are fine if they fit the parts and everything, but just to use a name for the sake of using a name is not necessarily a positive thing."

However, Eastwood publicly curating his cast (minus Piazza, who stars on "Boardwalk Empire") from various stage productions -- Young came from Broadway, Bergen from L.A. and Vegas, and Lomenda from the national tour -- did have one nasty side effect. According to Bergen, an all-out, deadly war broke out when news spread that Eastwood was looking.

"I actually had one person killed," Bergen, who plays bandmember and songwriter Bob Gaudio in the film, said with a laugh. "Which we're not going to talk about."

We won't tell anyone if you won't.

"Jersey Boys" hit theaters on Friday, June 20.
