I have four, mostly already mentioned:
Vincent Schiavelli
Brad Dourif
Harry Dean Stanton
Joan Cusack
I know there are more women, but names are escaping me at the moment. I'm famous for the spontaneous squee during a movie or a show -- "I know her! She's in everything! I love her!"
But I did enjoy watching people threaten his life, Corwood.
Madonn', how did I forget the salami-brain? Probably because I always say "Look, it's Crosetti."
Or for that matter, "Was that Giardello?"
Okay, two more women (I am blatantly disregarding the rule of three):
K Callan and Micole Mercurio
Jane Addams
Lois Smith
Alice Drummond
Addams played the ex-wife in Sideways and has been in a lot of indie films or tiny roles in larger movies. Lois Smith is older and has been in EVERYTHING. She was the wise older woman Tom Cruise visits in Minority Report. Alice Drummond often plays older, slightly batty women.
I forgot Eve Arden! Amazing in movies from Mildred Pierce to Grease!
Joan Blondell is in
Grease
, too!!
Shirley Henderson
David Straitharn
Martin Donovan
Timothy Spall
Jim Broadbent
I ADORE all of Sue's list.
What else has Shirley Henderson been in other than the Harry Potter films and the ShakespeaRetold of Taming of the Shrew (in which she was great, btw)?
I was going to add Kelly Macdonald, but she's on the cusp of leading/character actor.
