I was about to post a reply then I fell asleep and my computer restarted. I could only think of a few films that starts with an M in the beginning, but now it's really coming out of the woodwork. No googling.
My Left Foot
My Cousin Vinny
Me, Myself, & Irene
Moonraker - 007
Monster (w/ Charlise Theron)
Men At Work
Mannequin (great 80's cult favorite)
Mulan...hahaha...I don't know how I came up with this one.
Mobsters (this took awhile to think of)
Marcus Aurelius: Tell me again, Maximus, why are we here?
Maximus: For the glory of the Empire, sire.
Baked, not fried... the healthy choice.
