Superstar Shah Rukh Khan says shooting for his forthcoming film "Fan" has been a difficult journey as an actor, but says he still doesn't have any clarity on how people love him so much.

"Before I could become a fan, I became a star. I still don't understand how people love me so much... care for me and their mothers and children and families (also shower affections). It is quite a responsibility for me sometimes...," Shah Rukh noted.

In Maneesh Sharma's "Fan", slated for a April 15 release, SRK essays a fan obsessed with a reigning superstar who looks just like him, and travels to Mumbai to meet the actor.

Quizzed on how he juggled playing the role of an obsessed fan, SRK said it felt "quite schizophrenic" to do that.

"One has to maintain a dignity of what a fan is. That part I have kept in mind. It's been a difficult journey as an actor... quite schizophrenic ... quite dichotomous."

The "Dilwale" star revealed his take on stardom and clarified that he is not a fan of himself.

"Not at all... I am amazed that I should have become a star. My general belief is people who become actors are people who do not love themselves. They just want to be a different person every morning. People who love themselves become extremely fantastic stars. So I am not a big fan of myself," he added.

The 50-year-old actor was in the city on Monday to launch Nerolac Paints' coffee table book 'Shades of Bengal'.
