Rock & Roll may never die, but in the latest project from writer-director Dan Fogelman (the writer of Crazy, Stupid, Love and Last Vegas taking the helm for the first time here), it seems like it might be on its last legs. The titular hero (Al Pacino) is a rocker of some renown in the twilight of his career facing the fact that his glory days are behind him and he’s likely about to walk off the stage alone, until he discovers a letter John Lennon wrote to him more than 40 years ago. The note leads Collins to make some significant life changes, which can’t be easy for an old dog of his ilk. (Opens Friday, April 10 at Kenwood Theatre) (R) Not screened in time for review
