Director Apoorva Lakhia and Zayed Khan had a heated argument on location for Mission Istanbul in Istanbul.

Says Lakhia, “He wanted to do a risky stunt himself. I refused. We rehearsed it with a double. But at the last minute Zayed was adamant. He insisted on doing it even as I protested.

As the whole unit in Istanbul watched with mouths open, Zayed Khan crashed through a glass window and plunged to the street down below from the 8th floor of a high-rise into a truck on the road.
