A young and superhot Jack Nicholson, at the height of his acting powers, is maverick sailor Billy "Bad Ass" Budduski; a very young Randy Quaid, at the apex of his spazziness, is the virginal young sailor Budduski has to deliver to navy prison. The plot takes the sailors on a road trip to seedy 1970s diners, whorehouses, and bars to show the cracked-up Quaid one last good time before the brig, and the result is one of the best American films ever made. Darryl Ponicsan, who wrote the novel Detail is based on, will introduce the film. (Northwest Film Forum, 1515 12th Ave, 329-2629. 7:30 pm, $8.50.)
