Nawazuddin Siddiqui, considered among the most accomplished of contemporary actors, is himself an unabashed Sridevi fan. He had to pinch himself when he was offered Mom with the veteran actress.

"When I got a chance to work with Srideviji in Mom, I couldn't believe it. It was more than a dream come true. It's my good fortune that I got to share screen space with her," the actor says.

"As a viewer, I would always wonder how she managed to be so perfect in every film, every character. As a co-actor, I still don't know how she manages to be so flawless in every take," says Nawaz, who flaunts a new get-up in Mom.

He goes on to add, "We tend to use superlatives to describe many artistes whom we like. And we often say about an actor or actress that he or she is one of the best. But with Sridevi, I can say with full confidence and certainty that she is the best actor in the world. No two ways about it."

How and where does this certainty about Sridevi's supremacy come from?

"After getting the rare privilege and opportunity of working with her in Mom. I was always her fan. Big fan. She has always been my favourite actress. Srideviji and Bachchan saab were always my favourites. I'd sneak into a theatre close to my home to watch their films whenever I could," he says.
