When Ali didn't believe it, and spoke to Dhawan about it, the comic director joined into the prank too, and said 'yes'.
Ali was apprehensive and shy, but later gave in and started rehearsing for the same along with Siddharth and Divyendu. During the rehearsals, every time Ali would strip, everyone on the set would start rolling in laughter.
Puzzled by everyone's behaviour, Ali later realised it was all a prank, said a source.
Produced by Viacom 18 Motion Pictures, Chashme Baddoor is a remake of the 1981 film of the same name. The movie hits theatres April 5.
