While shooting at Marine Lines, Imran Khan had a tough time with his fans while trying to protect his film's look

Imran Khan was shooting in the vicinity of Liberty theatre at Marine Lines a few days ago. As his look in the film is not out, the crew was very careful about guarding it.

Says a source, `We had tight security on the sets to protect his look from getting out. However for one scene he had to step out of the cinema hall and shoot in the bylanes. This is when people began gathering and were keen to meet Imran. When the crowd went out-of-hand, the shoot had to be stopped.`

Director Milan Luthria adds, `His fans got to see his look which I had been guarding. I was paranoid when I saw the crowd. Now I hope no one leaks it. I have been requesting Imran not to spend too much time outside the sets when he is shooting at public places. But sometimes it is unavoidable.`
