Me too. I had Christine Baranski and Margaret Dumont (she was in a lot of Marx Brothers films)

Here's some other I've thought of:
girls:
Hattie McDaniel (one of the best, I just remembered her..)
Kathleen Freeman (in hundreds of movies)
Bobo Lewis (she was on a lot of old tv shows)
Josephine Hull (Mortimer's Aunt Abby in Arsenic and Old Lace)
Marion Lorne (Aunt Agatha[i think] on Bewitched)
Mabel Albertson (Darren's mom from Bewitched)
Marjorie Main (Ma Kettle)
Agnes Moorehead (I love her old movies)

guys:
Marty Feldman (Young Frankenstein)
Paul Lynde (i love this guy)
Alan Hale Sr. (in a lot of WW2 movies)
Arthur Treacher (plays the butler in a lot of movies)

There's also a guy I see in just about EVERY WW2 movie I've ever seen.. but I can never find out his name. But he's good too. But my all time favorite is Peter Lorre. Love him.
