I know it's not weekend but...
Monday!
Desperado - Awesome fight scense. DVD has an
'anatomy of a shootout' feature that tells how they direct the shootouts. Awesome.
S.W.A.T - It was okay. I liked the way they did the news-camera type effect. I hated the one guys face though.
Underworld - Had good effects and monsters and stuff... didn't care for the story though.
