"When I came in the industry, I was fortunate enough that my film worked. But it worked because the subject was good. That's what I am desperately looking for - a good subject for my son," Sunny, who entered filmdom with 1983 super hit film "Betaab", told IANS.
There were reports that Anil Sharma, who directed Sunny in hits like "Gadar - Ek Prem Katha", will helm Karan's launch pad.
When asked about it, Sunny, 57, said: "Sharma has spoken to him, but it all depends on the subject."
The "Ghayal" star tried his hand at direction with "Dillagi", but has no intention of getting involved in his son's film as a director.
He said: "I may not be directorially involved with my son's project, but definitely, I will be involved in whatever he is doing. Whatever experience I have, I will make use of it."
