There are others I might think of first on a different day, probably Bette Davis or Barbara Stanwyck.
Loy could have chemistry with anyone — and was always funny. I also like how she played dramatic scenes without going BIG like so many did during that time. But I’m mostly familiar with her roles starting with the Thin Man and after.
Vincent Price was game to play and do anything. He always seemed to enjoy whatever he was doing, no matter how silly it might seem. I think my favorite performance of his is in The Abominable Dr. Phibes. It’s purposely ridiculous but has Art Deco sets and a fully committed Price playing a doctor seeking vengeance.
I love "The Abominable Dr. Phibes!" One of the rare horror movies I like. Vincent is definitely enjoying that role. (On a side note, when my mother saw the movie, it was shortly after my father had died and she was not happy with doctors. When the unicorn is catapulted and gores that doctor through the heart she laughed so loud and hard! She loved it.) Myrna Loy also did some great work in the silent era. She was usually a dark-haired temptress, so she really has great range. And Barbara Stanwyck is good in everything she does. Even that episode of "Charlie's Angels."
