"Sidharth and I are brothers competing with one another as authors or writers," said Fawad here.
About the film, he said: "'Kapoor & Sons' has a lineup of other great actors. Sidharth, Alia, Rishi sahab (Rishi Kapoor), Ratnaji (Ratna Pathak Shah), Rajat sir (Rajat Kapoor)."
"All of them are fantastic actors and great people to work with. We're hoping to see that it releases sometime in the first quarter of next year."
The film is directed by Shakun Batra and produced by Dharma Productions.
There are reports that Fawad, a popular Pakistani actor who made space in Bollywood with "Khoobsurat", has several films coming his way.
To that, he said: "I'm in discussions with other filmmakers, but nothing has been finalised. Having said that, nothing has been refused as well...constantly going back and forth on the ideas right now," he said.
