"I think Deepika is eager to play different characters and she wants to explore herself as an actress...that's very interesting. She is number one in this industry and she can keep on doing these glamorous roles and can secure her space in the industry, but she is experimenting," Irrfan said.
Irrfan Khan says he had a "great" time working with her. He asserts that more than chemistry with Deepika, he was concerned about finding "a common thing between the two to bond over".
"More than the chemistry (between Deepika and me in the film) I was concerned whether we will have something common between us where we can bond," the actor told.
"I still remember her first reaction after our first shot and I was pleasantly surprised. I was sure that something is going to happen. So I had a great time working with her," he added.
This is the first time that Irrfan and Deepika will be seen together on screen. Directed by Shoojit Sircar and written by Juhi Chaturvedi, Piku also features megastar Amitabh Bachchan in a key role. The film is slated to release on May 8.
