If you get through this new trailer for Rock the Kasbah without laughing, you should see a specialist.

The (objectively) funny new clip, exclusively on Yahoo Movies, reveals much more story from Barry Levinson’s comedy starring Bill Murray than we saw in trailer numero uno.

Murray plays the down-on-his-luck Richie Lanz — a sort of aged version of the sleazy rock manager he portrayed back in the ‘70s on Saturday Night Live named Jerry Aldini. Murray also drew inspiration for the role from Van Morrison’s real-life tour manager, whom the actor described during his recent surprise Comic-Con visit as a “pathological liar… a wonderful guy.”

In the film, Lanz stumbles into the role of talent scout for the Afghan version of American Idol (called Afghan Star). As seen above, he goes on a globetrotting hunt that leads him to a string of offbeat characters played by the likes of Zooey Deschanel, Bruce Willis, Kate Hudson, and Danny McBride. Lanz finally unearths Salima (played by newcomer Leem Lubany), his singing ingénue.

From what we’ve seen from Kasbah so far, the film evokes both the legendary 1987 bomb Ishtar (which later gained a dedicated cult following) and Almost Famous — for which Kasbah star Hudson earned an Oscar nomination and which also featured Deschanel in a supporting part.

Written by Murray’s longtime pal Mitch Glazer (Scrooged), whose friendship dates back to their SNL days, Kasbah opens in theaters Oct. 23.
