Alan Rickman in anything. He could read the phone book and I'd love it.
Ralph Fiennes in Schindlers List & the English Patient, but boy has he made some turkeys (Maid in Manhattan anyone?). On stage in Ivanov he was brilliant.
Ewan McGregor in Moulin Rouge (also the only film I've ever liked Nicole Kidman in)
Kenneth Branagh on stage and film in just about anything
Daniel Day Lewis on stage in Hamlet was amazing, and I count myself extremely lucky that I was fortunate enough to see it.
Juliet Stevenson - I would watch her in anything
Kate Winslet, good, but can be patchy and over the top, but I love her anyway.
Emma Thomson - the only decent thing in an otherwise diabolical Love Actually.
I'll stop now Ooh, and Michael Caine, just because.....well, he brings class to anything, even if he's only doing it for the money
No, I really will stop now!
