Sunny had announced in 2010, "My son will be launched in a year. I am looking for a good story for him." Karan was among the first batch of students at Rahul Rawail's acting school. More recently, he assisted Sangeeth Sivan through the making of 'Yamla Pagla Deewana 2'. Reportedly, Sunny asked the director of his biggest blockbuster 'Gadar---Ek Prem Katha' to come up with a suitable launchpad for his 22-year old son.
Sharma, whose next 'Singh Saab The Great' with Sunny in the lead, opens on November 22, has almost locked his script, and is waiting to show the final draft to the protectivc father. When contacted, Sharma did not deny the story, but said, "It's still too premature to talk about it."
