The 43-year-old director said in a recent interview that the 50-year-old actor is beyond family to him, reports the Dawn.
He added, "In fact, my equation with him has moved from him to his kids now. I always tell him that I am going to maintain my youth quotient only because I want to launch Aryan. No one else can launch Aryan but me."
Not only this, Karan credits his career as an esteemed filmmaker to SRK, along with Aditya Chopra.
He said, "Shah Rukh was the one who felt that I could be a film-maker. Working with him hasn't just been an honour but a big thing for my career. When he chose me, it was a big deal for me."
Karan further said, "Working with him has taught me everything about movies. His technical expertise and intuition as an actor has made me a better film-maker. It was them who made me realize that perhaps I have the potential to become a director. Otherwise, it didn't cross my mind."
