Irrfan, whose filmography boasts of films like 'Maqbool', 'Life in a... Metro', 'The Namesake', 'The Lunchbox', 'Jurassic World' and 'Life of Pi', however, is of the view, a star should overcome the self-doubts and concentrate on his or her performances.
"Every superstar has some insecurity. If a movie of a director becomes hit, then the star wants to work with him. He thinks the director gave a hit with others so I'll work with him too.
"That is why a superstar is in search of choosing new subjects. Insecurity is everywhere. But if you carry the burden of insecurity always and if it is affecting your performance, then that's a big problem," Irrfan said in an interview.
The 48-year-old actor's upcoming project, Sanjay Gupta's action drama "Jazbaa", will see him sharing screen space with Bollywood diva Aishwarya Rai Bachchan.
The 'Piku' actor said, despite her stardom, Aishwarya is a grounded person.
"She has a very larger-than-life image but she is very simple. She takes care of people around her and is unlike the big superstar image she has. She is very grounded."
The movie marks Aishwarya's return to big screen after a gap of five years but Irrfan never felt she was away from movies.
"Comeback from where? For me she was always here. She didn't go anywhere. An actor should be allowed a gap. Her audience is still with her. People are her fan, her admirers, and they'll definitely go to watch her," he said.
