"Every film has its own space. I am happy that in the recent past there are three or four films which have done great business. When it comes to box office, I hope even my film is good enough. We hope we will be able to touch the success of those films," said Shah Rukh who is anticipating breaking the Bollywood box office records by his dream project.

"I have worked as an actor and producer in the film and I would love to get double returns," he added.

'Ra.One' which would be release in more than 3000 prints all over India is expecting to yield a distributor share of around Rs. 55-60 crore from Indian theatrical markets in its first week and around Rs. 40-45 crore from the overseas markets.

The 45-year-old Khan, who is busy in promoting "Ra.One", wants this dream to memorable as he plans to quit smoking after the film's release.

"I am waiting for 'Ra.One' to release and after that I will quit smoking once and for all. At least I will try," he said.
