[Help! Two women spat/fight!]

That's it! I love this scene ("Oh no! I don't want to take the last piece!). I really appreciate your quick and accurate response. Thanks a bunch!

[Help! Two women spat/fight!]

I am trying to recall a movie that I cannot remember even the stars! Maybe Cary Grant or James Stewart. But there is a party and one woman (Barbara Stanwyck?) lures the other outside and calmly strikes her. They trade blows with one woman being cool as a cucumber through the whole scene. I hope this gives enough info. It was maybe the best spat scenes I have ever seen and dying to watch it again. Can't get it out of my mind. Thanks.
