They failed to recognize the veteran actor with the makeup and spoke to each other for a very long time.
According to the sources, the scene required Shakti to shed his normal avatar and undergo metamorphosis. The makeup man was put on a mission by the MCDS makers to make him look like a woman. But, his body structure made it evident that he was a man in disguise.
So, in between shoot, Shakti got up to attend a call and waited outside for a while, when the androgynous males surrounded him. The veteran actor too, thought of it as a test and convinced himself to pull it off in front of them and began talking to them.
After discussing on various topics for sometime, the actor came back and said that he was ready for the next shot!
