Producer Prerna Arora, who is backing a biopic on Olympic gold medallist shooter Abhinav Bindra, says it is a difficult project as the makers have to be cautious while presenting the story in an honest way.

It is the first time Prerna is working on a sports biopic, and she believes a lot of responsibility comes with such films.

"With this project we have to be accurate, we can't afford to make mistakes with the content. The scripting is still on. It is in development stage. It will go on floors either December or early next year," Prerna said.

Recently, the biopic on flight attendant Neerja Bhanot was embroiled in a controversy after her family locked in a battle with the producers of the film Neerja over its box-office profits.

Earlier, legendary sportsman Milkha Singh had accused director and co-producer Rakeysh Omprakash Mehra of not fulfilling his commitment of sharing the profit of his biopic Bhaag Milkha Bhaag.

However, Prerna says she will make sure her film does not face such issues.

"Today, taking the rights of the person for a film, on whom it is based, has become essential. We have to respect this collaboration. We will be making sure that nothing goes wrong.

"We want to give credit to every person who is attached to the film personally as well as professionally."

Prerna says Bindra is helping makers in understanding and bringing his life story alive to the big screen.

Prerna, who spearheads Kriarj Entertainment Pvt Ltd, made her debut in Bollywood as a producer with Akshay Kumar in Rustom.

She has three films lined-up, including John Abraham's Parmanu, Anushka Sharma's Pari and Akshay Kumar's Padman.

Prerna is also set to back Sara Ali Khan's debut film Kedarnath, which also features Sushant Singh Rajput and Vishal Bhardwaj's next starring Deepika Padukone and Irrfan Khan.

Her latest released Toilet: Ek Prem Katha stars Akshay Kumar and Bhumi Pednekar.

"The biggest challenge in such films (of social cause) is reaching out to a wider audience and trying to understand how many people are taking the film and the subject seriously.

"Also, promoting the film in the right manner possible plays a major role and making sure it (film) passes the right message.
