Entertainment Gallery Introducing Aaliya,Sahir (Katrina,Aamir) from ‘Dhoom: 3’ Yash Raj Films' famous 'Dhoom' series is all set for its third installment. The film is known for its action sequences but more than that for the ingenious anti-hero it gives. While the previous installments saw the likes of actors John Abraham and Hrithik Roshan,in its third chapter YRF has roped in Bollywood's Mr Perfectionist Aamir Khan to end the series with a bang. The poster of Aamir Khan introduces him as the 'clown thief' Sahir. Dressed in all black and a trendy hat,Aamir Khan holds a burlesque clown mask in his hand,that may be his signature in the film (like Hrithik had an 'A' symbol). Bollywood's Barbie doll Katrina Kaif is out of her comfort zone in the film and is set for some thrilling action sequences. Katrina is Aaliya the acrobat diva. The teaser trailer of the film too showed Katrina flaunting some acrobatic moves,which will make her an interesting watch. Abhishek Bachchan is back as 'Super Cop' Jai Dixit. Abhishek is all set to give the clown thief a tough time with his astute presence of mind and understanding. Last but not the least we have Uday Chopra as ace biker Ali. Uday Chopra too reprises his role as Jai Dixit's sidekick! The film which is set to release on December 20 will indeed set the curtains on 2013 with a bang.
