Of course you would like Welcome to the Dollhouse, Frankie! I love that movie .
There are many faves for me, although I do tend to have more fave directors and films rather than specific people. Here are a few though-
Benicio Del Toro, Philip Seymour Hoffman, Sharlto Copley (I think his only film is District 9 but I loved him in it!), Kate Winslet, Emma Thompson, Mark Ruffalo, Forrest Whitaker, Scarlett Johannson, Kevin Spacey, Jeff Bridges, Russell Crowe.
