Tigmanshu Dhulia plays SRK's father

Director Tigmanshu Dhulia, who will be portraying the role of superstar Shah Rukh Khan's father in Anand L Rai's next, which has SRK playing a dwarf, says he wanted to be part of the project to see how it is done.

"I do very few films as an actor. It's only when a filmmaker friend feels that I can do justice to a certain role that I take it on. This is a technical film, where Shah Rukh is playing a character of dwarf. So I wanted to see how it is made, because when Kamal Hassan (Appu Raja) did it, he did that with folded legs since VFX wasn't available," Tigmanshu said at the trailer launch of his upcoming film Raagdesh on Thursday.

"So to know that process, I did this film. It's a very time consuming film, where you have to give the best effort because you have to shoot each shot with 3 to 4 different approaches. Each day, they only used to complete only one scene, so it's a hard film to make," he added.

Talking about the challenges that he faced while working on Raagdesh which is based on the 1945 Red Fort Trials, when the Indian National Army soldiers were court martialled by the British, Tigmanshu said, "When you are writing a fictional story, you can use your imagination to pen a story. But when you have a real story, and you have to mould it into a proper film script, then it is challenging; especially when you don't have the permission to tamper with past facts." 

"Each scene of this film is documented with the help of some or other book, so I haven't had any opportunity to take cinematic liberty in this film," he added. 

Raagdesh features Kunal Kapoor, Amit Sadh and Mohit Marwah in lead roles and is scheduled for release on July 28.
