For a sequence in the movie, Rajkummar Rao advised the crew to use his real blood and not artificial blood to get a more realistic look.
To transform into the role, Rajkummar Rao ate only carrots and coffee for the 20-day film shoot.
Trapped premiered at the 18th Mumbai Film Festival in 2016 and reportedly received a standing ovation from the audience.
When director Vikramaditya Motwane read the script for the movie, he immediately knew that actor Rajkummar Rao would be a perfect fit for the role of Shaurya.
Trapped is Vikramaditya Motwane's third feature film directorial venture. His first film Udaan was selected to compete in the 'Un Certain Regard' category at the 2010 Cannes Film Festival.
