Some who I like a lot (without necessarily knowing much about them): Jennifer Jason Leigh, Johnny Depp, Tim Burton, Emily Watson, Sofia Coppola, Jean-Pierre Jeunet, Wong Kar-Wai, Juliette Binoche.
Plus some who I like a lot, but with an asterisk (ie, I like 'em a lot, but while either (a) also kind of disliking them or (b) generally feeling ambivalent about liking them): David Lynch, Terry Gilliam, Baz Luhrmann, George Clooney, Catherine Zeta Jones, Cary Elwes (though probably only because of the recent rewatch of The Princess Bride), Christina Ricci, Gwyneth Paltrow, Audrey Tautou, Tim Roth, Tilda Swinton (sometimes one role, even in a Hollywood blockbuster, is enough), Bill Murray, Scarlett Johansson, Miranda Otto, Steve Buscemi.
And a few who I've liked in the past but seem to've left behind: Winona Ryder, Jennifer Connelly, Janeane Garofalo, Edward Norton (though I still think he's a brilliant actor), Gary Oldman (likewise), Christopher Walken, Lars von Trier.
