Bollywood superstar Shah Rukh Khan is reportedly planning to come up with a sequel to his science fiction superhero film "Ra.One".

In an recent interview, the "Chennai Express" star revealed his intention to make a sequel to "Ra.One" but said it would take time due to lack of trained technicians required to make science fiction flicks.

"We have the latest technology and the equipment, but we lack trained technicians. For Ra.One, we had hired 50 foreign-trained technicians. I would love to work in Ra.One 2, but it's not easy. For a film with a different genre like 'Ra.One', I'll need at least two to three years for preparation," Shah Rofukh told IANS.

"Ra.One", starring Shah Rukh in a double role and Kareena Kapoor, hit screens in 2011. The film was a big budget project of about ₹150 crore and has around 3,500 VFX shots.

Being one of his most ambitious projects, Shah Rukh worked with Jeffrey Kleiser, co-founder of US-based Synthesian Studios, who assisted the actor's Red Chillies VFX team in the making of the film.

Recently, the special effects team collaborated with makers of upcoming superhero flick "Krrish 3" which stars Hrithik Roshan.

"For Rakesh Roshan's film, 'Krrish 3′, the equipment is from our company. We have trained over 200 technicians in the last five years. They are very good, but the vision has to come from Rakesh Roshan. If you have the vision and technology, the technicians can be changed," Shah Rukh said.

He went on to add that Indian filmmakers are ready to take risks these days, giving reference to films like Anurag Kashyap's "Gangs of Wasseypur" and Anurag Basu's Barfi!.

"There have always been all kinds of filmmakers who make films like 'Iron Man', 'Batman' and 'Chak De! India' at the same time. It's always parallel. When I did DDLJ (Dilwale Dulhania Le Jayenge), there was 'Maya Memsaab' too. There are 'Gangs of Wasseypur' and 'Barfi!', all kinds of films being made. It is good," Shah Rukh said.

The actor concluded by saying that he will try to work on films from a different genre. "I feel the industry has given me name, fame and money and I won't ever forgive myself if I won't do anything beneficial for Indian cinema and my fans," he said.
