Rumours are flying that Aamir Khan is to play a cannibal in his next home production.Apparently Aamir has been eager to find an interesting script for a long time and finally zeroed in on the idea of playing a psychic man-eater. The movie is likely to be directed by a top director from the South, after working with A. R. Murugadoss in Ghajini, Aamir has taken a liking for South directors.A source has reportedly said, "The actor is busy preparing for the role. To get into the skin of the character, Aamir has been visiting butchers in town to see how they cut meat. Aamir is also on a high-protein non-vegetarian diet to build his muscles for the role. He is also watching the behaviour of all animals very closely to bring in a 'beastly' touch to his character."Talk about getting into character!
