this is simple. all the characters above, 1 person. every role he plays is totally different from the previous one. he steals the limelight even though sometimes he may not be the lead. he is terrific playing iconic characters/people. hawking, van gogh, sherlock, frnakenstein, khan, julian assange etc etc. his portrayal of these characters never let us down, it is uncannily accurate in everything from the twitches, body language, accent. it is never an impression or a stereotype, but rather a true portrayal of the character inside out. phenomenal actor, incredibly charismatic, very knowledgable and articulate, unbelievably nice and polite, has a good sense of humour. his acting, at times subtle, at times dramatic, but always captivating.
2. Robert Downey Jr
RDJ is fascinating. he is witty, entertaining, funny, charismatic all together. also an incredibly talented actor and singer. no matter where he is, what role he is playing, he steals the limelight and everyone's eyes seems to be focused on him. his portrayal of chaplin is terrific (should have gotten an oscar in my opinion), in tropic thunder, he is a dude playing a dude disguised as another dude, he is irreplaceable as iron man, and his sherlock is pretty good (although i feel that Benedict Cumberbatch's version may be better).
3. Meryl Streep
ok… meryl streep is a legend. she is possibly the greatest actress ever. 3 oscar wins and 17 nominations. who can beat that. she holds the record, and will hold it for a long time to come. when she is in character, she is gentle, fierce, crazy, ruthless, weak, joyful, calm, agitated, aggressive, firm, sometimes all at the same time.
4. Anne Hathaway
anne hathaway is incredibly talented, constantly defying expectations in her choices and performances. in princess diaries, she is hilarious to say the least. in rachel getting married, she shocked audiences by giving an extremely raw, emotional, courageous performance as a recovering drug addict. in love and other drugs, she plays a patient with parkinsons. people doubted her when she was announced to play cat woman, but she silenced critics and was a revelation, and arguably my favourite character in the dark knight rises. and of course, in les miserables, there are no words to describe how unbelievable her performance was.
5. Christian Bale
body transformations, weight lost then weight gain, then dramatic weight lost again. Christian Bale is never physically the same in any two of his movies. the lengths he goes through to totally embody his characters is astounding and i respect him a great deal for that. the roles he chooses to play are incredibly challenging too. roles like his characters in the machinist, american phycho, the fighter etc would have been incredibly cliche and difficult to watch if taken on by a lesser actor, but he is phenomenal.
