Dancing with Hrithik was the biggest challenge

Hrithik Roshan, considered one of the best dancers in Bollywood, is seen doing some high octane dance moves in his upcoming film ‘Bang Bang’ and his co-star Katrina Kaif says she had to try hard to match up to the actor.

The 31-year-old actress is playing the female lead in the action thriller, which is the official remake of the Hollywood film ‘Knight and Day’ starring Tom Cruise and Cameron Diaz.

"Dancing with Hrithik was the biggest challenge. His flexibility is incredible. It is at a different level altogether. You have to be really good to match up to his energy. He has natural energy when he dances. It comes to him so effortlessly," Katrina said during the launch of the title track of the film in Mumbai.

When asked who was the better dancer in the song among the two, the ‘Dhoom: 3’ actress said till the time of the rehearsals she was doing fine, but Hrithik just blew everyone away during the final shoot.

"I was ok during rehearsals because Hrithik was not dancing! Finally when we danced on the sets, we all know who danced better," said the actress, adding that the title song ‘Bang Bang’ is one of her favourite tracks.

‘Bang Bang’ has been directed by Siddharth Raj Anand. He says the film is a very important project for him as he has invested a lot in the movie.

"It has been a journey of blood, sweat and tears for me and a very difficult one. I am very emotional right now and might cry because this is the first time I am talking about all of it. But I am feeling happy now," he said. The film also stars Danny Denzongpa, Jaaved Jaffrey and will hit theatres on October 2.
