Actor Aamir Khan, who is all set to play a gymnast in Vijay Krishna Acharya’s thriller Dhoom 3, is reportedly shooting for his introduction song and several other scenes in circus tents at Film City. Media reports have quoted a source as saying, “He will be indulging in trapeze and mid-air acts for the shoot. The place has been booked for a good long 40 days. European dancers and performers will be performing with him in the song.” Meanwhile, Bollywood’s Mr Perfectionist has been devoted to get the right look for the film.

The actor will be sporting a leaner and fitter look in the film. “Aamir is seen pumping iron around the sets. He wants to be fit as a fiddle. He has been training day in and day out for his look keeping his diet in check despite his other commitments," a Mid-Day report quoted the source. The film also stars Katrina Kaif, who has been cast opposite Aamir in the film. The Bollywood diva too is said to have taken special training in paragliding and singing to fit her role in the film.

The film slated to release on December 25 will see Abhishek Bachchan and Uday Chopra reprising their roles as Jai Dixit and Ali Khan. Actress Rimi Sen, who had essayed the character of ACP Dixit's wife in the prequels, was not approached to play her character Sweety. However, in a previous interview, the actress’s spokesperson had said that she wouldn't have done the role even if she were offered. With so many big names attached to it, this is going to be one film to watch out for this year.
