‘Dhoom’ had John Abraham and Esha Deol, ‘Dhoom 2’ had Hrithik Roshan and Aishwarya Rai; and now in ‘Dhoom 3’ are Aamir Khan and Katrina Kaif! Abhishek Bachchan as ACP Jai Dixit and Uday Chopra as Ali Khan have been the only common factor in all. Aamir Khan for the first time in ‘Dhoom 3’ is essaying a full-fledged negative role. Aamir has really worked hard to get into the character of Sahir the ‘Clown Thief’. He even went to Australia for a hush-hush trip to train in tap dancing and ballet. Aamir plays a circus gymnast in ‘Dhoom 3’. He will be seen doing a trademark movement in various songs and action scenes. ‘Dhoom 3’ is the third film that Aamir is doing under the Yash Raj Films Banner, the first was ‘Parampara’ way back in 1990. Abhishek Bachchan lost around nine kilos of weight for the role. Katrina Kaif also took professional paragliding lessons to prepare for her role as ‘Aaliya’. Written and directed by Vijay Krishna Acharya; the action-thriller film is set to release on December 20, 2013. We wish the entire team of ‘Dhoom 3’ all the best!
