While talking to ANI on the same, the 49-year-old said, "I was in a creative cave while making that film. Nobody knew that I was making 'Poorna.' For 14 months, nobody knew. I kept it a secret because I never wanted anybody else to take the story and make the film."

Stating that 'Poorna' was a very difficult film to shoot, Rahul said, "This film was tough to shoot, because we started at 40-45 degrees in Pakala village from a hut, where Poorna grew up and then we moved to Bhongir of 650 feet high, where one shot would take one and half to two hours."

'Poorna: Courage Has No Limit' is a biopic on the youngest girl, in history, to climb Mount Everest, Poorna Malavath. She was only 13, when she climbed the Everest.

The film takes the audience from the young girl's small hut in Telengana to Bhongir Fort outside Hyderabad, to Darjeeling and Sikkim, to Nepal, and then to the top of Everest.

It has also got some of the unreleased footages of Poorna's journey to Everest.

When ANI quizzed on how he managed to get those footages, the actor-turned-director said, "We have some of the best footage from the summit of Everest that people would ever see. However, I won't reveal now how we did it."

The film, starring Aditi Inamdar as Malavath Poorna and Rahul as Dr. R. S. Praveen Kumar, the cop who inspired Poorna to scale Mount Everest, is all set to hit the theaters on March 31.
