Director Tigmanshu Dhulia has turned into an actor by playing the role of Shah Rukh Khan 's father in Anand L Rai's next film. Tigmanshu says he wanted to be part of the project to see how it is done.

The actor quipped, "I do very few films as an actor but when a filmmaker friend feels that I can do justice to certain role -- and when I need some money -- then only I do a film. It's a very technical film in which 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, that time he did that with folded legs and VFX facility also wasn't available."

"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 and in each day they only used to complete only one scene so it's a hard film to make, but they are giving their best effort for that," he also said.

Talking about the challenges, Tigmanshu said: "When you are writing a fictional story, that time writer can use his imagination to write a story, but when you have real story, then you have to mould it into 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 the other books, so I haven't had any opportunity to take cinematic liberty in this film," he added in last.
