Two guys walk into a bar--that's the plot. Not much of a plot, you have to admit, but when the two guys are Tom Waits and Iggy Pop and the director is Jim Jarmusch, the results are well worth watching.Winner of the Palme d'Or for Best Short Film (whatever that's worth), this is 12 minutes of prime Jarmuschian minimalism, filmed in B&W. Waits and Pop, playing themselves, have a Pinteresque exchange at a diner "somewhere in California," with the former becoming testier by the minute and the latter trying fruitlessly to win him over. They talk, in an aimless way, about coffee and cigarettes. Like a well-done short story, the film is economical and punchy, making its wry point with no wasted effort.This is the third, and the most recent, in a series of related films that Jarmusch has been working on for years. I for one hope he can keep it going.
