"As an actor, I feel that having done a big film, 'Happy New Year', I wanted to do a cosy film which is intense and yet commercially viable. Maneesh came out of the blue and he reminded me of a subject he had narrated eight years ago," the 48-year-old told reporters in a group interview.
"I was sitting with Adi (Aditya Chopra) and instantly agreed because I was in a happy state of mind," he added.
Shah Rukh also says that he is not sure if "Fan" will cross Rs. 200 crore mark but he is happy to do the film.
"I don't know whether the film (Fan) will do Rs 200 crores business or not, but I have to be in a similar state of mind as the director who wants to cast me. Five years back, a film I was supposed to do got cancelled and I called Ashutosh (Gowariker) and Ramu (Gopal Verma) but no one had any film for me.
"The timing has to be right. What restricts my choice of films is the directors - they are the ones who cast me," said King Khan who has reunited with his "Main Hoon Naa" and "Om Shanti Om" director Farah Khan for his latest release "Happy New Year".
Produced by Shah Rukh's Red Chillies Entertainment Pvt Ltd, the film is a heist drama and also features Deepika Padukone, Abhishek Bachchan, Boman Irani, Jackie Shroff, Sonu Sood, and Vivaan Shah.
The superstar, who generally does one film at a time, says this time he will be shooting for two films "Fan" and "Raees".
"I do one film at a time which everyone does. But right now I am doing two films. I would have liked to wait for two months after 'Happy New Year', but I have already finished a 20-day schedule for 'Fan'. Thereafter, 'Raees' will be over in 60-70 days if it goes as per plan," he said.
