One of my favorite movies...
I have my own copy that is a Christmas tradition at my house (along with Barbara Stanwyck in "Christmas in Connecticut"). I just love those old movies with the non-stop witty dialog, zingers, and all the cultural references flying by at a prodigious clip. But then, The Man Who Came to Dinner was originally a play by Moss Hart.
I love it when Bette punts Lorraine's muff after they lock her in the mummy case.
