For the Karjat schedule of 'Prem Ratan Dhan Payo', Salman Khan has apparently been using a body double to shoot for the better part of the day.

An insider reveals that Salman Khan stays on the set for just about three to four hours after which his lookalike takes over.

The superstar essays a double role - a prince, Prem, and a streetfighter, Vijay - in this Sooraj Barjatya drama.
