Global megastar Shah Rukh Khan says the character he portrays in the Karan Johar's film Kabhi Alvida Naa Kehna is a complete 180 degree turnaround from the idealistic lovers he has portrayed with such aplomb, which have helped make him the megastar his is today.

Speaking on Tuesday to the media in Mumbai, SRK said unlike the 'Raj' and 'Rahul' type characters he has played in blockbusters like Dilwale Dulhaniya Le Jayenge and Kuch Kuch Hota Hai, respectively, his character 'Dev' in Kabhi Alvida Naa Kehna is cynical and sarcastic. However, due to director Karan Johar's conviction, the character will be likeable.

"I would not have done this film, if somebody else had been the director," he added.

Shah Rukh said Kabhi Alvida Naa Kehna has a 'bold theme', "It is bold not in the sense of sensuality, sexuality or the language used. It deals with the subject of vulnerable relationships with dignity." He added, "The focus is on what happens when relationships go haywire."

When asked about co-star Abhishek Bachchan in Kabhi Alvida Naa Kehna, SRK said, "Abhishek is a well-behaved boy. Unfortunately, we do not have many scenes in the film. He is hard working and very funny. We had good time shooting for the film in New York".

To the question as to who has been his best co-star so far, SRK quipped, "Myself in the film Duplicate".

On another note, Shah Rukh spoke about his new venture, a VFX studio started by his production house, 'Red Chillies Entertainment'. SRK said the effort is to bring quality into visual effects used in films.

"We have got a couple of visualisers and operators who are experts in this field and getting good business. The company will take up work for outside producers as well. The special effects of my film Don, directed and produced by Farhan Akhtar, is done here. The company will also do the special effects of my home production Om Shanti Om", he related.
