Love, love, love rocky horror picture show! I can do the Time Warp
I have a random assortment of other favorites:
Edward Scissorhands
Charlie and the Chocolate Factory (hate Willy Wonka, but love this one, I think all in all I like all of Tim Burton's movies, I'm really excited for Sweeny Todd this Christmas)
Sweet Home Alabama
Harry Potter's
The Wedding Date
In Her Shoes
I've watched all of these movies so much that I've worn some of them out and need to get new ones. It's to a point that dbf can recite them I've watched them so much
