The Princess of Wales Theatre is no stranger to music, and last night was no exception at the premiere of Can a Song Save Your Life? The John Carney film stars Keira Knightley, Mark Ruffalo, and Adam Levine in his first acting role. Carney himself walked the red carpet alongside the film's cast members. Also on hand were supporting actors Catherine Kenner and Ian Blodsky, as well as musician Rufus Wainwright. Can a Song Save Your Life? is a story about finding love and fame in the music business. You can catch it at the Ryerson Theatre tonight at 8 p.m. and on Saturday, September 14th at 12 p.m.
