/> In Samir Karnik's Yamla Pagla Deewana Dharmendra and Bobby Deol play a father-son con-men duo in Varanasi.

Sunny plays an upright man married to a Canadian living in Canada who 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. Karnik will shoot in Varanasi in April.

The interesting part of the film is the bum-chum relationship between father Dharmendra and son Bobby, when in real life Bobby is intimdated by his father.

Laughs Karnik, "Not so any longer. Thanks to the preparation for my film both Bobby and Sunny have loosened up with their Dad."

While Bobby is paired with television actress Kulraj Randhawa, the Canadian leading lady for Sunny is yet to be finalized.

The film's shooting starts on Feb 15.

"And we release Yamala Pagla Deewana on December 24, Aamir Khan's slot. This year he won't have any release in the last week of December. So we've decided to release our film in that a slot, " announces Samir Karnik.

Incidentally Karnik's lucky mascot, little Dwij Yadav who features in all of the director's works so far, won't be part of Yamla Pagla Deewana.

"Let him grow up off camera now. He's my insurance for the future, just like Rakesh Roshan has Hrithik, " says the director emotionally.

The film's title is obviously inspired by the chartbuster Main jat yamala pagla deewana from Dharmendra's 1975 blockbuster Pratiggya.

Karnik intends to record a remix version of the Mohd Rafi hit. The director introduces a new composing duo Nouman Javed and Rahul Seth, one of whom happens to be from Pakistan.

Says Karnik, "I heard Nouman's music on the internet and asked him to send me his songs on the MP3 format. Then I took another new composer Rahul Seth to Dubai and we recorded the songs in a Nouman's land (Dubai)."

While doing a re-mix of the old hit may be considered a stroke of clever marketing, bringing the father Deol and his two sons together hardly qualifies as a novel strategy.

Says Karnik, "I know Dharamji, Sunny and Bobby have been brought together earlier in Apne. But that was a very emotional drama. Yamala Pagla Deewana is an out- and- out comedy."
