It seems Imran and Minissha have shot a chilling underwater sequence in the film, which is among the highlights of the film and also the point when she gets kidnapped. Both the actors rehearsed for the scene for almost a fortnight before taking the 'dive!
Confirms director Sanjay Gadhvi, "We trained in Mumbai in a pool. It was an elaborate shoot with a dedicated underwater DOP and a standby team of divers for rescue.
I've used the same underwater specialists as the ones used in Dhoom:2. While shooting the scene I was on the boat watching the shot on the monitor, which was attached to the underwater camera by cables.
We had special communication equipment through which Imran and Minissha could hear me say 'action' and 'cut' while they were underwater."
