"It was a wonderful experience. Whoever is thinking of becoming an actor or taking a training, should observe Mr Bachchan. Otherwise, he/she will never be aware of the nuances of acting," Irrfan said at the trailer launch of the film yesterday.
"Mr Bachchan follows his director's vision in a very obedient way. At the same time, he is very playful too.
Sometimes when a person is hardworking that can be boring for other people. But I will always remember his playfulness."
The film, slated to release on May 8, is about a working daughter and her father. Irrfan plays an interesting character in the mix of father-daughter. The actor said he enjoyed the experience of working on the movie.
"With both Deepika and Amitabh Bachchan it was magical and inspirational and an outstanding experience. And as Bachchan saab says even I was emotional at the end of the shooting," Irrfan said.
