It would be nice to see a sharp, funny, penetrating satire of the new, kicked-up culture of empty media fame, but Tom DiCillo's scattershot buddy movie Delirious isn't it. Steve Buscemi, as an abrasive New York paparazzo, is way too overbearingly scuzzy and ''on edge.'' For no good reason, he makes a homeless pretty boy (Michael Pitt) his assistant, and the film turns into Repo Man crossed with Midnight Cowboy, propelled by a kind of generically scruffy indie-movie natter. Then Pitt gets famous, which allows DiCillo to make his big point: that paparazzi are forever on the outside looking in.
