He reasons that he had no reference to the character in romantic thriller "Ek Villain", in which his role is that of a man with grey shades.
"To do an action-oriented and intense film right after doing romance is far more taxing because real life references are not there.
"Neither am I such a kind of person in real life nor do I know somebody with such personality. So, in that case, you have to work much harder, do homework as an actor, have to work on your look and this is what I have tried to do in the film," the actor told reporters here Tuesday at Lawman Pg3 store.
He hopes to do a range of films and characters post "Ek Villain".
"Hopefully after 'Ek Villain' I will get more films where I can do both positive and negative characters," added the 29-year-old, who turned to acting after being a successful model and working as an assistant director.
