After his first Bollywood film Rang De Basanti, South actor Siddharth wore the serious actor tag thanks to his role in the film

He followed it up with Striker that sank without a trace. In his third outing, Siddharth is hoping that he has a drastic change of image with Chashme Baddoor.

Unit sources state Siddharth's amusing antics would often leave the film's director David Dhawan in splits. Says a unit hand, `When it comes to comic situations, Davidji is the master of ceremonies. But once in between shots, Siddharth did a disappearing act during a break.

He returned on the sets in a totally different get-up. He came back wearing a turban and fake beard, which probably was the costume for some other artiste in the studio. Siddharth was curious to know how he would look if he sported the look and that's what led him to try it on.`

Adds the source, `The entire unit cracked up on his arrival and Davidji was mighty amused. The director even went on to do the bhangra with him.`

No wonder at a recent event Dhawan was heard saying that Siddharth is turning out to be the naughtiest of them all!
