"Fan", directed by Maneesh Sharma and produced by Aditya Chopra, will feature the Bollywood 'badshah' playing a fan.
"Finished once again a 15 hour gruelling day of satisfying work on Fan. Thanks Maneesh & ur Fan Team...being so nice to me & smiling along," Shah Rukh tweeted.
SRK, whose recently revealed eight-pack abs in "Happy New Year" has caught eyeballs galore, had earlier said that the movie is dedicated to his fan following.
"'Fan' is a 'family film'. It's the family all of you have become for me...the one I didn't have. I want to be as beautiful as you all. Thanks," he had once said.
