In an effort to make every manâs girlfriend resent him, director Steven Soderbergh has been filling the cast of his male stripper movie Magic Mike with way too good-looking guys left and right. Channing Tatum, Alex Pettyfer, Matthew McConaughey and recent addition Matt Bomer currently make up the âare you kidding me?â cast, and now three more names have been added: Joe Manganiello, Jessica Biel and Riley Keough.EW reports that True Blood star Manganiello will play a stripper named âBig Dick Ritchieâ (but of course) in the semi-biographical film about Tatumâs teenage days as a male stripper. Lest the cast be too dude-heavy, E! Online reports that Riley Keough (The Runaways) will play a girl who dates Pettyferâs character, an up-and-coming stripper, and ComingSoon reports that Jessica Biel has signed on to play a stripper named Amber who also happens to be Manganielloâs squeeze. Filming begins next month in Florida, where Iâm sure the cast will remain fully-clothed for the bulk of the movie.[Update: Variety's Justin Kroll tweeted that he's been told Biel has passed on the role, so file her casting under rumor for now.]
