Oh my, it's difficult to come with 5 favourites just out of the blue but here goes........
The Birdcage (I laugh everytime I see it, especially when the Hank Azaria (sp?) character trips over his shoes)
Something's Gotta Give - love that house!
Saving Grace (British comedy)
Grease
Most movies in the romantic comedy / chick flick genre - can't think of one that I like the best)
And then there is the "anything with Colin Firth in it" category :lol:
