This is the poster for The Rocker (click image to enlarge), a comedy starring Wilson that's due this summer. Wilson plays a guy who got kicked out of a hair band in the 1980s and now, 20 years later, joins his nephew's upstart band as a means of reclaiming his former glory. The director is Peter Cattaneo (The Full Monty), with a screenplay by Maya Forbes (various Larry Sanders Show episodes) and Wally Wolodarksy (various Simpsons episodes).
The release date is Aug. 1, but it's premiering at the CineVegas Film Festival in June, so we should have a review for you then. The premise is good, the cast (which also includes Christina Applegate) and personnel are good, and August has been a fertile month for comedies in recent years (Superbad, Talladega Nights, 40-Year-Old Virgin), so we're keeping our fingers crossed for this one.
(And is it me, or is this poster a tad Apatow-esque?)
