The 58-year-old 'Gadar' star will serve as the director for the project, which he will start working on after seeing the response on his current movie.
"After 'Ghayal Once Again' I will talk about my son's debut. That is the next thing I will be working on," Sunny said in a interview here.
The actor, whose film 'Mohalla Assi' made headlines for the abuses in the trailer, said he does not understand why people go away from the very essence of the subject, just because it has cuss words in it.
"'Mohalla Assi' is a nice subject... One should try and understand deeper into it, which we never do. There are no abuses in the film which we have put forcefully. We lose the subject and go offtrack," he said.
Sunny has become very particular when it comes to choosing his films and the actor considers lack of exciting scripts responsible for his absence from the big screen.
"I am not getting any good scripts. I am eagerly waiting for something good to come my way. We are talking about 100 crores, 200 crores but nobody talks about people liked it or not. That is sad and I am not in favour of it," the 'Yamla Pagla Deewana' actor said.
"I am keen to work with any director, who is not full of himself, but full of the subject," he added.
After spending over three decades in Bollywood, Sunny has managed to keep a clean image and shares a good rapport with everyone. However, he says he does not share personal bond with any of the industry insiders.
"We are colleagues. We are not enemies. Enemies are those, who keep fighting till they kill each other. Friendship is always till school. That's the era of friendship, after that everything is professional."
Produced by Dharmendra, 'Ghayal Once Again' also stars Om Puri, Soha Ali Khan an Tisca Chopra. The film will hit thescreens this Friday.
