'Life of Pi' is an adaptation of Yann Martel's bestselling novel of the same name and tells the story of a boy named Pi Patel and his incredible survival at sea against impossible odds.
The 45-year-old actor plays the grown-up Pi in the film that marks the "Brokeback Mountain" helmer's first 3D creation.
"'Life Of Pi' is going to be an exceptional film. It is based on a very intelligent book. It was very difficult to adapt it into a film but the director did a fantastic job with it.
"It is Ang's first 3D film and I am sure people are going to like it. With this film he has done something extraordinary," said Irrfan, who was in the Capital to attend the ongoing 12th Osians Film Festival.
"Life of Pi" also stars Suraj Sharma, Tabu, Adil Hussain and Hollywood star Tobey Maguire. The fantasy film will hit Indian theatres on November 21, a month ahead of its US release.
Irrfan's latest Hollywood release, Marc Webb's "The Amazing Spider-Man", saw him play an important role as Dr Ratha and he said that the success of the film came a surprise to him.
"I never had any hopes for that role. I was not expecting anything. I enjoyed working with the director and I am happy that the film is doing so well. I am also very happy for Andrew (Garfield, who plays Spider-Man in the film). In the end it feels good to see a film succeed," he said. (MORE)
