"I wish Yashji (Yash Chopra) had seen the film, he would have really liked it... He would have been really happy to see 'Fan'. We miss him," Shah Rukh told PTI.
The actor also said that Yash Chopra never narrated him the film's idea.
"Maneesh Sharma (director of 'Fan') narrated me the idea of 'Fan' and they (media) thought Yash Chopra. Maneesh narrated me the idea 13 years ago, Yashji was not aware about it," he said.
SRK had starred in Yash Chopra's last directorial venture "Jab Tak Hai Jaan".

The much-anticipated movie "Fan" will feature Shah Rukh in a double role, a superstar and his look-alike fan.
For the 50-year-old actor, playing a superstar and an obsessive fan was physically draining. Shah Rukh is hopeful that the audience will enjoy the film.
"There are no songs in the film, except one. It's a pure experience of story telling... It's a new way," he said.
The "Swades" actor was amazed with the research put in by
Maneesh for getting things in the right order for his on-screen portrayal of superstar - Aryan Khanna.
"The collection of things that Maneesh (director) and his team had was amazing. They took me to a room where they had everything. It was like a fan's room. They had all my photos, including videos, my first interview," he said.
"Adi (producer Aditya Chopra) asked me to check the room. They had been researching for six-eight months," he added.
"While we were trying to device a voice for Gaurav (fan in the film), they made me hear my own interviews as my voice was thinner and younger in the earlier times," he said.
"Lot of things in the film are derivatives of what I might have said on screen in films. Like a love dialogue (in 'Fan') is not from any film, but it is a derivative of the love dialogues that I say (in my films)," he added.
The upcoming thriller also starring former model Waluscha de Sousa and veteran actor Sachin Pilgaonkar's daughter Shriya, opens in theatres on April 15.
