Bollywood has witnessed several smashing debuts in 2015. Harshvardhan, actor Anil Kapoor`s son, will make his debut with Rakeysh Omprakash Mehra`s `Mirza Sahibaan`. Sonam`s younger brother has been away from the prying eyes of the media, which increases the curiosity about this Kapoor lad. In fact, sister Sonam seemed nervous about her brother`s debut. She is happy that brother is in the film industry, but feels very nervous because he is a kid. Harshvardhan was Anurag Kashyap`s assistant director for his film `Bombay Velvet`. Sachin and Supriya Pilgaonkar`s daughter, Shriya, is all set to make her Bollywood debut with Shah Rukh Khan. During the shooting for `Fan` in New Delhi Shah Rukh talked about Shriya presence as she is a part of the film.  Shriya has a small but important role in `Fan`. Ace comedian Kapil Sharma will debut with Abbas Mastan`s film opposite Elli Avram. Kapil brings with him a huge fan following following his mega success as a versatile actor and anchor on his superhit TV show `Comedy Nights with Kapil`. So accepting him will be easy for cine goers and movie lovers. Karan Singh Grover, the heart throb of the telly world, made his Bollywood debut with `Alone` opposite none other than Bipasha and won rave reviews for his performance.
