Looks interesting. Below info from The Playlist plus more info & photos in the link:
“CBGB,” an upcoming cinematic chronicle of the famed New York music venue, features a veritable who’s-who of stars playing the great and good (and bad!) of the punk rock scene which centred on the venue in the 1980s. Justin Bartha plays Stiv Bators (of Dead Boys), Malin Akerman plays Blondie lead singer Debbie Harry, Mickey Sumner plays Patti Smith, Rupert Grint plays the Dead Boys guitarist Cheetah Chrome, Foo Fighters drummer Taylor Hawkins is Iggy Pop with Alan Rickman as the legendary Hilly Kristal, the founder of CBGB.
