I caught this movie on a premium channel and was blown away by its sexual frankness, its amorality, its great acting and directing. Javier stood out although Rosie was his match but I'd seen her before, especially in "White Men Can't Jump" where she stole the movie from W's Snipes and Harrelson.
Javier was so cool being so "bad'. His choices since then have been all over the map; he hasn't been stereotyped into a heavy although he was plenty heavy in "Old Men...". I'd hate to see him stuck in heavy hell for the rest of his "Hollywood" career. By the way, I think the Coen brothers suck.
