'Bang Bang' is more than just 'Knight and Day' remake, says Hrithik Roshan

Bollywood star Hrithik Roshan says his upcoming film Bang Bang may be a remake of Hollywood movie Knight and Day but the action thriller has its own elements which will make it very new to the audience.

The 40-year-old actor has donned an action hero avatar in the Siddharth Anand-directed movie, which was portrayed by Tom Cruise in the original movie.

"Only the thought of Knight and Day is there in Bang Bang otherwise it is a complete new film. If you are not aware of the comparison then it will never occur to you while watching 'Bang Bang'," Hrithik said during the launch of Bang Bang game.

The actor says when Siddharth offered him the film, he instantly said yes to the project because he loved the idea of the character which is cool and fun. "I said yes to the film in 5 seconds. The single most important reason for me doing this film is the idea. I always wanted to do a film like this. Before I spoke to Siddharth, I had watched Knight and Day on a flight. And I told myself I want to do a film like this which is cool and fun. Post Dhoom 2, I had not done anything closer. I was very keen to start this film," he said.

In the trailer of the movie, Hrithik is seen doing some daredevil stunts while on a bike, jet-skiing and fly-boarding. When asked if he finds doing action scenes difficult, the Krrish 3 star said that the stunts are challenging for sure but he maintains his cool while performing them.

"It has been 15 years since I am doing this. It is challenging and tough but practice makes you perfect. While doing it one should be very careful and focused. It's a calculated risk. It's always in your mind. When you conquer your fear that is a very accomplished feeling. I loved conquering that fear," he said.

In Bang Bang, Hrithik is reuniting with his Zindagi Na Milegi Dobara co-star Katrina Kaif and their sizzling chemistry is already making waves. "Chemistry is always on the paper. It's a vision of a director. You have to be inspired about the love story. When two honest actors read the script they can create that chemistry on-screen. Katrina is very hard working and a go-getter. She will go all the way to get whatever she wants to achieve and that is very commendable," Hrithik said.

The actor also said that his two sons- Hrehaan and Hridhaan- love the teasers of Bang Bang and are looking forward to the release of the movie. "They are at the right age and have started liking my film. Probably for the first time right from teaser to the songs my sons have really liked the film. I am very proud and happy that they have liked it. It's a very special feeling," he said.

Bang Bang, which also stars Danny Denzongpa and Jaaved Jaffrey, will hit theatres on October 2.
