Howl's Moving Castle is a good one! As are the other Miyazaki films.

Arsenic and Old Lace
Benny and Joon
Big Fish
Bringing Up Baby
Dirty Rotten Scoundrels
Labyrinth
Lost in Translation
My Blue Heaven
Nick and Norah's Infinite Playlist
Princess Bride
Raiders of the Lost Ark
The Addams Family
The Dark Crystal
The Neverending Story
When Harry Met Sally
Willow

ie, anything and everything from my childhood. We watched Dirty Rotten Scoundrels sooo often as a kid; that would probably be my first go-to choice out of this list. I also love love love sitting down with old horror films after having a troutty day or during a rainy day (but I love the rain, so).

I think I am going to do just what Auly mentioned (wine?) and watch one of these tonight!
