The idea of Cargo came to director Arati Kadav in 2017 after she worked on pre-production for a film for six months before it got shelved. After getting angry at the situation, Kadav started writing another script and after 2-3 months, she developed an idea. A friend of her Rahul Puri had told her that film school Whistling Woods International was going to be free for a month and its studio space, camera and some lights will be available for shoot. She started thinking about what could be made in a single location and pictured a spaceship. Kadav wrote a “complicated massive intergalactic superhero story” for the next three months but later realised it was too expensive to shoot.
