Check out "The Best Food Movies, by Farr:"
I haven't seen most of these. But, yes, Silence of the Lambs ranks high on my list, too. I would also submit:
Chocolat
Diner
9 1/2 Weeks
Bridget Jones Diary
Mystic Pizza
Flashdance (because of that scene with the lobster)
Julie & Julia
The Godfather trilogy (because they're always eating, and because of the oranges)
Fried Green Tomatoes
Do the Right Thing
The Secret Lives of Bees (the book was a thousand times better)
Waitress
