"Grand Hotel"The only one you haven't seen is the only one (on that list) I have seen. Then again, I'm not much of an old-time movie buff.
"Ms. Minerver"
"West Side Story" (only Best Pic I've never seen)
"Oliver!"
"Marty"
"Midnight Cowboy"
Either way, be sure to catch "West Side Story." It's a great show, music and all (yes, Peter, musicals do have redeeming value.)
