Bollywood superstar Shah Rukh Khan says his upcoming sci-fi superhero film "RA. One" is an attempt to create something that will change the genre of Indian films.

"It's an indigenously made film and it's made in VFX studios in India and is trying to create something which will change the genre of films. If Indian filmmakers would like to make something alike, they have the access to the technology, " King Khan told reporters at FICCI-Frames Friday.

He also said that the film would be his first step in paying back to the audiences the love and honour he has received in the last 20 years of his career.

"I have made one promise to every one in India. I have been working for 20 years and I have been given too much; much more than I deserve as an actor, as a star, and I think it's time to give back some, " the superstar said.

"RA. One" is scheduled to release at Diwali time but the star has already started its marketing so that the superhero character sinks into the psyche of his audience.

"I just thought that we don't have any background of a superhero in terms of comics like 'Spiderman'. We have superheroes like 'Krrish' and 'Drona' but they are film superheroes.

"I tell people this is the one who's gonna do. . . he is going to fly, he has these powers and once this becomes known, then people would like to come and see the film. . . I just thought to market a year before, hope it pays off, " Shah Rukh said.
