Mumbai, Jul 22 (PTI): Director Imtiaz Ali, who has teamed up with Shah Rukh Khan for the first time for "Jab Harry Met Sejal", says the superstar never brought his stardom to the set.

"Working with him was like working with any other actor. You realised he is a big star only when you see the crowd around the sets. Otherwise, the way he carries himself and participates in a film, you don't get the feel that he is a star," Imtiaz told reporters here at the trailer launch of the movie.

"We both are from theatre background so it was easy to communicate with Shah Rukh. It was easy to work with him. He is a basic theatre actor for whom the story and the co-actor is important. He is the only giving actor I have worked with," he says.

Imtiaz credits his mother for suggesting the basic idea of the film about a tour guide.

"One day my mom told me to make a film where I would shoot at different places so that she could come and visit these places. I said in that case I should make a film on a tour guide and there will be a girl in it.

"I had met Shah Rukh sir and he was asking me if I have a story and I said I have one 'cheap' story. He seemed interested and said, 'We should make this'."
