Mumbai, April 22 (IANS): Actor Rajkummar Rao, who will be seen in a key role in Hansal Mehta's forthcoming film "Aligarh", says the film does not have an "out-of-the-box" story to tell, but it entails a social cause.

"It's not a different story, but has a message of a social cause in it. It is a human drama with an emotional element," the actor said here on Tuesday at the Dadasaheb Phalke Film Foundation Awards.

"It is not an 'out-of-the box' story but it is a beautiful story and I feel lucky to be a part of it," he added.

"Aligarh" is reportedly based on the real life incident of Shrinivas Ramchandra Siras, a doctor who was terminated from his job because of his sexuality.

In the film, actor Manoj Bajpayee plays Siras, and Rakummar says he had a "great experience" working with him.

"It was a great experience. He (Manoj Bajpayee) is great artist and a great human being as well. I have always looked up to him," the National Award winner said.

For Rajkummar, Bajpayee's work has been a learning experience.

"His work has always been a learning process for me and now that we are working together, I'm learning a lot from him."
