premise: The film, directed by Steven Soderbergh, would be worth seeing just for Stamp's performance, at once rock-hard and goofily blinkered, and for Peter Fonda's wittily self-parodic turn as the suspected killer, a music producer who coasts on '60s counterculture easiness while his lackeys do the dirty work.
hypothesis: It's worth watching the film just for the sake of Stamp's performance.
