I actually downloaded Sean of the Dead off the Net (first time I've ever tried that). I keep attempting to get to the theatre to see it, but stuff always seems to pop up. Haven't watched it yet, but I'll catch it tonight or tomorrow.
Last movie that I saw in a theatre was Dodgeball, I think. I found it very funny.
Maria, Full of Grace sounds good, if only because it's one of those titles that could also be the title of its porno version with no changes at all ;)
They could also do a TV version called Maria, Full of Will and Grace ...
