Two of the biggest players in Bollywood currently Ekta Kapoor and Karan Johar also happen to be thick friends.

So when one of Ekta's films required a scene from Karan's Kabhi Khushi Kabhi Gham, there was simply no reason for Karan to refuse

The promo for the sequel of Ekta's upcoming comedy film begins with SRK's introductory sequence in K3G, and for Karan, it was a nice way to induce some nostalgia through the trailer.

Says a source, "The film is a mix of various spoofs and gags and a laugh riot. So they thought it would be interesting to contrast it with another film that represents anything but spoofs.

K3G represents family cinema in this country and so it was interesting to club the two together."
