Steve Buscemi is everywhere this summer. He's great in Delirious, a sharp satire from writer-director Tom DiCillo (Living in Oblivion) that takes a tired subject (the fame game) and makes it fiercely funny and touching. Buscemi plays Les Galantine, a Manhattan paparazzi scrounging to grab a shot of pop tart K'Harma Leeds (Alison Lohman) that might earn him a few hundred bucks. He takes in the homeless Toby (the excellent Michael Pitt), an actor who serves as his assistant until Toby hits it big and dumps Les. In a movie of easy targets, DiCillo gratifyingly takes no cheap shots. And Buscemi makes this pathetic and potentially lethal shutterbug a figure of surprising humor and compassion.
