LONDON - Shah Rukh Khan sent his fans wild Tuesday at the U.K. premiere of his new Bollywood blockbuster "Ra.One."

The Hindi film icon and co-stars Kareena Kapoor and Arjun Rampal received a huge reception on the red carpet at London's 02 Arena.

"Ra.One" sees Khan take the lead as Shekhar, an embarrassing father who creates an amazing game in a bid to impress his streetwise son. Unfortunately, the plan backfires when the game turns against them.

A 3D science fiction-superhero adventure may seem like quite a change from usual Bollywood films, but Khan insists that it's "not so different."

"We still have singing and dancing, so it's all there," he said.

Indian media say the special effects-heavy movie is set to be Bollywood's biggest-ever release, opening in approximately 5,000 screens worldwide. Khan, however, says it's not been made to try to compete with Hollywood blockbusters.

"I think one of the few things we need to go ahead in is the technology and the way we make our films and tell our stories," he said. "So yeah, it's a step towards that, but it would be too big to say that it would compete with an international film."

"Ra.One" opens in the U.K., India and worldwide on Wednesday.
