The achingly romantic and hopeful Gatsby is played impeccably by DiCaprio. He has aged into a beautiful man while still possessing those boyish good looks. The beginning of the film has the viewer itching to see Gatsby and hear him speak, and when he finally appears he holds on and captivates throughout the film. The film may awaken something in you, a memory of when you were crazy in love with a person or in love with an idea for what your life should be. DiCaprio embodies a dream and makes you root for him, even though he is shown to be a liar and a man who is desperately trying to steal another's wife- all that does not matter because we see the gentle child-like frailty in him and identify with it. DiCaprio is an excellent actor and was perfect for the role.
I must say that I didn't think that Mulligan can pull the role of Daisy, who in my mind was supposed to be a flawless beauty. However, she didn't disappoint. It made Gatsby's love and desire for her even more fascinating- she was beautiful to him and that's all that mattered. Mulligan was able to play the spoiled and dazed rich girl well, while adding an emotional dimension to the character. Tobey Mcguire definitely held his own, and his story line had an interesting deviation from the novel which was enjoyable. All in all I think it is a must see this year for movie buffs.
