Some of the ones that impressed me the most are:
Ralph Fiennes, Schindler's List - The way he captures such a monstrous character is so convincing it is downright chilling
Ellen Burstyn, Requiem for a Dream - Absolutely heart-breaking in how raw her portrayal is
Heath Ledger, The Dark Knight - It's a cliché perhaps but the way he just completely disappears into the character to the point where the man himself is invisible is mind blowing stuff.
Anthony Hopkins, The Silence of the Lambs - An instant classic for bringing such a charismatic psycho to live so vividly
