Ben Kingsley As Mohandas Karamchand Gandhi – Gandhi (1982)

If there’s one actor who was born to play Mohandas Gandhi, it’s Ben Kingsley. He did the part so well that when he met an elderly peasant while filming, the old man actually thought he was Gandhi. The short time it took for Kingsley to prepare for the role didn’t deter the British actor from his determination to portray it in the best possible way. He gave his all to the character he played, he said, that at the end of the film there’s no more trace of the Gandhi left in him. His determination did pay off because even to this day, it’s hard to look at Kingsley without seeing at the back of your mind the iconic role he once took on.

Val Kilmer as Jim Morrison – The Doors (1991)

Just how good did Val Kilmer portray The Doors frontman, Jim Morrison? He got so much into his character that at the end of filming, he needed to get therapy because it was difficult for him to get out of character. Although he wasn’t a The Doors fan, he wanted the role so much that for a year before filming, he lived like Morrison. Kilmer dressed in his clothes and immersed himself into listening to all The Doors music. Eventually, he talked, walked, and sang so much like Morrison that the film crew started to refer to him as Jim. Although the film did not get the critical acclaim its producers hoped for it, Val Kilmer was highly praised for his accurate portrayal.
