Sharman Joshi as Sherpa
Sharman Joshi is no idiot, although he made the box office records as an integral character of the hit film, 3 Idiots.
He is a method actor who chooses his role with care and a lot of thought. Sharman also plans out the character sketch and the graph the role should follow. So for the role of a Sherpa, the actor took a course in mountaineering. His make up artist studied how prosthetics can be used to give him the right look. Effects of chaffed and cold burns on the skin, reddened due to the harsh cold wind and cold, were studied and applied on Sharman.
After a month of preparation, Sharman started his shoot as a Sherpa for an ad film.
