We still remember the Nikhil from Happy Days – the raw guy who falls in love with the lecturer, the guy who tells her and then struggles to recite an English poem for her, the guy who begs the tomboy to write his records. With his boy-next-door looks, he got on just fine in that movie. He then went a bit off-track trying to do typical mass roles, but reinvented himself with Karthikeya. The supernatural thriller gave him a fresh lease of life, and since then he's been doing decent movies with slightly different story lines that have brought him a fair share of success.
