He made his Bollywood debut with 'Bus Yuhin' (2003) opposite Nandita Das. He took the offer firstly because he is aware that cricket is worshipped in India as a sport.
Secondly he is the solo anchour and all the contestants are females and also because the offer was from SRK's production house and it is only short term anchouring for six weeks. He feels SRK is a great entertainer and is an achiever all the way. He enjoys watching SRK films.
