Matthew,
A recent comedy flick, "Liar, Liar", an older comedy flick "Blazin' Saddles" (or maybe not, she might laugh so hard the baby will come early), and finally a person favorite "Educating Rita" (an adult film without sex, violence or foul language).
Oh, yes, "A Fish Called Wanda" would be nice. My son would recommend any of the Monty Python Pantheon. Obviously, I am free associating now!
