"Its official -- 3D version is ready for Wednesday and trust me it looks awesome. So see ‘Ra.One’ once in 3D and once in 2D at least. Am I being greedy," the 45-year-old posted on his Twitter page.

The grapevine was abuzz that the 3D version wasn`t ready and the release of the much-awaited film could be delayed. But Shah Rukh ended the speculation.

He is busy promoting and screening the film abroad. After a premiere in Dubai, he is in London now.

"In London now. Unbelieveable about a year back was throwing cars all around the roads of London...now will see it in 3D in O2," he added.

Shah Rukh plays a superhero in the film, which also features Arjun Rampal and Kareena Kapoor.
