While interacting with media at the trailer launch, Shahrukh Khan revealed that he came to know about Aanand L Rai's film from his good friend Salman Khan.
Shah Rukh plays the role of a vertically-challenged person in the film, which is set to be released on December 21. "It's not true that he (Rai) asked a lot of people... Salman had actually called me and said, there's this film, do it.' The reason he came and did that song was because of this. He wanted to be a part of the film, Shah Rukh said.
"Salman is a wonderful human being... For him to remember that a year later or months later when the film was actually being told to Katrina to come back and say I want to be a part of this film because I've heard this film.' It was very dignified, decent of him, he added.
