Can you suggest some good hollywood comedy movies?

Yes, I so love that movie it's sooooo funny LOL. If you want to watch some good comedies then you have to rent the following:

Liar Liar: starring Jim Carey
50 First Dates: starring Drew Barrymore & Adam Sandler
Tommy Boy: starring Chris Farley

and

Wedding Singer: starring Adam Sandler

i agree with the person above! 50 First Dates is great!
another comedy that gets me laughing no matter how many times ive seen it is Bowfinger..starring Steve Martin and Eddy Murphy (as 2 characters, the "brother" of which is friggin hilarious in facial expressions if nothing else!)
ive probably seen that movie half a dozen times now!

my favourite actor has to be either adam sandler or jim carrey 2 close 2 call really. so personally my favourite film by both actors are jim carrey in dumd and dumber, and adam sandler in happy gilmore. but i do like all the films they have both done apart from jim carreys man on the moon.
