Want to See A Movie With Bradley Cooper, Emma Stone, and Olaf the Snowman’s Josh Gad?

I am quite fond of a little film from 2008 called “The Rocker,” starring Rainn Wilson. And it’s even more fun now, as three of its actors have become big stars. Wilson plays a drummer who was let go just before his group became hugely successful in 1998. Twenty years later, his life is a mess and he is living with his sister and her husband (Jane Lynch and Jeff Garlin). His nephew (Josh Gad) has a rock group called A.D.D. that will be performing at prom, and they need a drummer. The group takes off — in both senses of the word. Emma Stone plays the group’s bass player. And Bradley Cooper is unrecognizable under a massive wig in a brief but funny as a member of Wilson’s original band, along with Will Arnett and Fred Armisen. The cast also includes Demetri Martin as the director of A.D.D.’s music video, Jason Sudeikis as their manager, and Christina Applegate as the mother of A.D.D.’s frontman, real-life musician Teddy Geiger. It’s a lot of fun and the music is great.
