In the other thread, someone mentioned how good the Brit actors/actresses are. I'm not really a movie buff but I always enjoy the powerful casts over the big budget movies. I read the article about the British Invasion in Hollywood in recent years. But I think British actors have already been a big part of Hollywood for the last 50 years.
For me, personally, I've been obsessed with Robert Carlyle since I watched the Full Monty. I love all of his works but Angela's Ashes is my favourite.
Also I love Judie Dench and Maggie Smith. Dench's Queen Elizabeth in Shakespeare in Love had less than 8 minutes screen times but it was the most memorable role in the entire movie plus won the Oscar too.
