sophomoric humor. And for a little while, that’s exactly what it is. At a certain point, however, Hill’s eyes look like they’re about to bulge right out of his head, and the movie’s satiric edge takes on a sudden inspired lunacy. When Hill and Brand show up in Las Vegas so the musician can reconcile with his deadbeat dad (Colm Meaney), Hill’s boss (Puff Daddy, firing crazy on all cylinders) enters the picture convinced that they can party Aldous into submission. This establishes a near-brilliant comic set-piece in which virtually every drug comes into play, as do firearms and pyrotechnics, with the breathless excitement of cast and crew working together in the service of a unified spoof. “Now this is what the music business is all about!” P. Diddy declares as the room blazes behind him. Talk about an indictment.
