The 48-year-old actor said it is always his endeavour to do unconventional things.
"I never thought of becoming an actor. I am here to redefine things... I hate conventional. It is not a thought-out process, it comes from within. It is God's given curse or blessing," he said.
The actor who has recently delivered a commercial success in 'Piku' and will be next seen as a rough cop in 'Jazbaa' alongside Aishwarya Rai Bachchan, says there is an instinct that pushes him to do different roles.
"I just go by instincts if the story is good, director and producer is good. But the first thing is you should like is the script," the 'The Lunchbox' actor said.
On his role in 'Jazbaa', he said, "I did not think of my role as a cop. I was thinking of the punch lines. My attraction for this film was punch lines which you will remember. I loved the character and the one-liners."
In the film's trailer, one can see the mention of megastar Amitabh Bachchan, to which Irrfan joked that he even sent an application to Bachchan to adopt him but it has not been approved yet.
Irrfan has come a long way from acting in television serials, including 'Chanakya- Bharat Ek Khoj' and 'Banegi Apni Baat' to do some memorable roles in both critically-acclaimed and commercial hit films.
His first movie role was a cameo in Mira Nair's 'Salaam Bombay' (1988) but he got noticed with Asif Kapadia's 'The Warrior'.
Irrfan's filmography includes movies like 'Maqbool', 'Metro', 'Slumdog Millionaire', 'Paan Singh Tomar', 'The Amazing Spider-Man', 'Life of Pi', 'Haider', 'Piku' and 'Jurassic World' among others.
