OK, so I'm really biased about this role (see aforementioned note about Robin Williams being my absolute favourite) and still thought that Will Smith crushed it. The Genie isn't the easiest character to play in a live-action film, we'd imagine, but Will managed to convey the high energy of Genie through the whole movie. He was entirely too much, but that's for sure how the character should be played. From his singing — and dancing — to the inside jokes between him and Aladdin (a great addition from the original script), your kids are going to be belly laughing at everything he says and does throughout the film.
