I can’t find a good clip, but I rather liked Ms. Day in the 1956 version of “The Man Who Knew Too Much”. (I liked Jimmy Stewart in that movie, too, but I think the 1934 version moves faster and has a more satisfying climax. Don’t get me wrong: both are good Hitchcock films.)
Peggy Lipton, of “Mod Squad” and “Twin Peaks” fame. I wish I had more to say about her, but I was just a little too young for “The Mod Squad” and pretty much missed “Twin Peaks” the first time around.
