Filmmaker Rajkumar Hirani has shared his experience of working with Shah Rukh Khan and said he was such a hardworking actor, India Today reported.

Rajkumar who has signed up King Khan for his upcoming film Dhunki, while talking about his first collaboration with him, said: "Working with him has been such a joy that it’s hard to describe. "

"He brings positive energy to the set and always makes everybody happy around him. I had no idea he prepares so much; I thought of him as an impromptu actor. When an actor is already prepared, it makes your job easier,"he said.

He further revealed: "He shoots videos of a scene at his home and sends them to me. There will be 15 ways of how he is going to perform this. Before I go on the set, I know what he is going to do. Sometimes I have kept two days for a shoot and he finishes it in two hours. He’s a complete charmer and has great control over the language. He surprised me completely by coming at 7 am to shoot."

3 idiots, Munna Bhai MBBS, Lage Raho Munna Bhai, and PK are some of the best works Rajkumar.
