Paul Giamatti is stepping into New Line’s adaptation of the Broadway hit “Rock of Ages,” starring Tom Cruise, according to Amy Adams is also in talks to join the film. 

Adam Shankman (“Hairspray”) is directing the big budget musical in which Giamatti will play the manager of glam metal rocker Stacee Jaxx (Cruise). Pop star Mary J. Blige and Alec Baldwin (“30 Rock”) will also appear in the film.
