Hah. I had bookmarked Donnie Darko because, while I had already watched it (good movie, even better soundtrack!) I wanted to watch it again with my wife. I swear it was available the week before I finally decided to rewatch it, then of course it was gone when I wanted it.

(By the way, I know this doesn't actually happen, but I swear Netflix sticks in my bookmarks movies and shows I never bookmarked!)
