Hrithik Roshan says he had to stretch his physical and mental limitations to do dangerous stunts for Yash Raj banner’s forthcoming thriller Dhoom 2 .

If Krrish consolidated Hrithik’s image as a superhero, ‘Dhoom 2’ will take it further. By Hrithik’s own admission, his stunts in the sequel to Dhoom are way beyond what he did in his father’s movie.

Even before shooting for the film, Hrithik had to learn roller-blading, snow-boarding, sand-boarding and stunts on motorbikes.

Stunt choreographer Alan Amin has designed some very difficult stunts in the film. The movie has a particular sequence that required Hrithik to train for two months. And there are as many as three such sequences in ‘Dhoom 2’.

Hrithik says although he did not train as much as was required for the stunts, he did undergo very arduous training for them.

For the pre-climax scene of the film, Hrithik had to do snow-boarding down a steep mountain in Durban.

The movie’s climax shows a chase sequence in a tunnel. The main part of the action climax was shot in Durban, South Africa. But the tunnel sequence was shot in Filmcity, Mumbai.

Not just Hrithik, even Aishwarya Rai has done some awesome stunts in the film.

When she began shooting for the film, the movie’s producer, Aditya Chopra, found her a little overweight for her role. So she did power yoga for two months to develop a perfectly toned up body.

Both Hrithik and Ash’s characters in the movie are shown very stylish. So, a lot of attention was paid to their styling. Hrithik's hair is colored almost blonde. Anahita Shroff is Hrithik’s stylist, while Blunt parlour has designed his hairdo.

Meticulous attention was given to the outfits of Ash. In the climax sequence, Ash has worn a black catsuit with dark goggles and open hair.

‘Dhoom 2’ looks like a very promising thriller. The movie has Hrithik and Ash playing thieves. Abhishek Bachchan , Uday Chopra and Bipasha Basu play cops.

The movie releases on November 24.
