Actor Sanjay Dutt is not nervous about his upcoming biopic as he believes his life, despite many controversies, has been an open book.

The 57-year-old actor, who is currently shooting his comeback film 'Bhoomi' after completing his jail term, is looking forward to the movie, which is being directed by 'Munnabhai' filmmaker Rajkumar Hirani.

"I'm not nervous about anything... Don't you all know about my life? And my things are out in the open. Bhushan (Kumar) is a big part of that film. I've just given my story and I've been with Rajkumar Hirani (while he was writing the film)," Dutt told reporters.

The actor says he chose Omung Kumar's revenge drama as his comeback film over a sequel because he appreciates good cinema.

"All my life I've been doing films which are original. I appreciate that people are recognising and appreciating that we're doing a film which we have thought about, we've written and is a film of a common man."

Dutt says he does not regret missing out on big budget films released in the last few years as he has worked in almost every genre.

"I have done every genre possible. I don't regret anything nor do I want to be a part of any other film. But yes, I do appreciate good cinema and good performances. It's only good for our industry that all the films should do well. Our industry should grow like that."

He may have served years in jail for being convicted in Arms Act but fans and the entire film fraternity have always loved him and wanted his comeback in Bollywood. Dutt says it is because of his grounded nature.

"I have been taught to be a good human, to respect people and be grounded no matter how big a person you become. That's what I've been taught by my parents."

The actor, who was convicted in the 1993 Mumbai serial blasts case, had served a 42-month sentence at Pune's Yerwada jail. He was released on February 25 last year, 103 days ahead of his prison term.

"I also want to clear that the tag of 'deshdrohi' (traitor) has been dismissed by court and I was proved innocent in that case. I was only convicted in Arms Act."
