Actor Gulshan Devaiah, who signed his upcoming film Mard Ko Dar Nahi Hota following knee reconstructive surgery, says he trained for months altogether for the part, but on set, he felt he knew "nothing" until he gave his first shot.

Vasan Bala's Mard Ko Dard Nahi Hota will see Gulshan in the role of a martial arts expert. The role required him to get himself prepared mentally and physically for challenging action scenes. Before signing the film, Gulshan went through knee reconstructive surgery on his right leg and was advised complete rest for upto one year.
