"Poorna" is based on a true story of Malavath Poorna, an tribal girl from Telengana who created history on May 25, 2014, by becoming the youngest girl in the world to scale the Mount Everest.
She was just 13-year-old when she pitched the Indian flag at 6 AM.
The actor, whose last directorial venture "Everybody Says I am Fine!" released in 2001, says he chose this particular story as it is inspiring.
"It's a visual feast as you start from a tribal village and ascend 29,000 ft to the top of the world, but most importantly, it is a story that as an Indian will make you laugh, will make you cry, will make you proud, will make you leave the cinema hall feeling six inches taller," the "Pyaar Ke Side Effects" actor added.
Aditi Inamdar, a Telengana girl, will portray Poorna on screen.
Aditi was chosen after the actor auditioned 109 girls, including a few tribals to bring Poorna's superhuman feat to screen.
