I feel this way about Judy Greer:
I've never gotten over her character in 'Jawbreaker'. And she's been in tons of stuff since then; but every time I see her I think to myself, "Bitch!" That's not really a fair thing to do (because it's slightly psycho for one thing), because she does sort of redeem herself in the movie, but I just can't help it.
Is there any actor like this for you? What was the movie and the role that you can't seem to disregard?
