After the release of RA.One, there was news that Shah Rukh Khan is keen to make a sequel to the hero flick.Shah Rukh's RA.One seems to have done business enough at the box office to enourage him to make a sequel. If sources are to be believed, Kareena Kapoor, we hear, isn't too keen to be a part of it, and this hasn't gone down too well with the Khan.If a sequel to RA.One is in the offing, we're told that Kareena won't be a part of it and that Shah Rukh is planning to rope someone else.
