"When Sanjay Dutt takes Aishwarya Rai, who is his wife in the movie to the
mountain cliff where she goes with Zayed Khan the other night,he shouts
loudly and `echoes` are heard.But that is impossible.......because echoes are heard only when there is a plain reflecting surface to reflect the incident sound and there is endless water in the direction in which Sanjay Dutt shouts.So did the echoes appear by magic ? "
