Mumbai : Samir Karnik's `Yamla Pagla Deewana' will see Dharmendra and Bobby Deol as a conmen duo. The directors say preparations for the film have brought the father and son closer.

Earlier Bobby used to be intimidated by his father in real life, Karnik said. "Not so any longer. Thanks to the preparation for my film, both Bobby and Sunny have loosened up with their dad," Karnik, who will shoot in Varanasi in April, told the media.

The film also stars Sunny as an upright man married to a Canadian living in Canada. He gets to know after two decades that he has a father and brother in Varanasi. The film is about Sunny's journey into his past and into a culture that he had left behind. While Bobby is paired with television actress Kulraj Randhawa, the Canadian leading lady for Sunny is yet to be finalised.
