Karan Johar breaks his vow, will be seen in a double role in this film

Karan Johar had vowed to never return on screen as an actor, post Bombay Velvet. But now, he’s all set to make his presence felt as one of the primary characters in the IIFA film — Crazy Hum — that also stars Sonakshi Sinha, Aditya Roy Kapur and Diljit Dosanjh.

The filmmaker has agreed to be a part of the film and he has a double role in it.

The movie, that was shot during IIFA, has other actors making interesting cameos too. “But Karan’s is a full fledged role,” adds our source. Or should we say, roles? “Details of his character has been kept under wraps. This is the biggest surprise of the film. The writers who are working on the set are constantly innovating everyday to enhance their script and it was then that they got this brilliant idea of having Karan’s duplicate.”
