Political activists allegedly threatened to disrupt Shah Rukh Khan's ad shoot with foreign artistes at Mehboob Studios in Bandra, but fled at the sight of cops.

Filmmakers have often faced trouble due to alleged interference by politically-backed film unions on the sets. Despite police commissioner Rakesh Maria's warning to such unions, sources say they recently targeted Shah Rukh Khan's ad shoot at Mehboob Studios.

A source says, "Shah Rukh was shooting for a commercial last Saturday night when a group of 50-60 political activists landed at the doorstep and threatened to stop the shoot. They objected to the producer roping in foreign artistes without permission and demanded to see their documents. The studio bouncers and members of the production team prevented them from entering the set."

A unit hand adds that the activists asked the producer to pay Rs 3-4 lakh as fine for employing foreigners. "When we refused, they started arguing and threatening us. That's when we had to call the police," the insider states.

Line producer for the ad shoot, Arpan Fernandes says that the shoot was disrupted for a few minutes, but resumed soon after the cops reached the spot. "The goons fled when the cops reached the studio. We had proper permission and work permit to rope in foreign artistes. Bandra police inspector Vilas Sutar was very supportive. I don't have any issues with any political party, but the racket needs to be stopped," he suggests.
