The trailer of Vikramaditya Motwane`s `Trapped` featuring Rajkummar Rao is out and it is sure to leave you intrigued!

Rajkummar Rao went through a physically and emotionally draining process to essay his role in `Trapped`.

"I was living on carrot and black coffee for `Trapped`. As we finished shooting the film within 20 days, to get under the skin of the character I didn`t eat properly and felt the frustration and anxiety of the character I play in the film," Rajkummar Rao told media at the trailer launch event on Wednesday in Mumbai.

"We approached the character very organically to get it right," he added.

The story of `Trapped` is woven around a young man, played by Rajkummar Rao, who is trapped in a room of a non-functional building for quite some time.

It was a challenge for whole team. While Motwane had to deal with the challenges of shooting in one room, Rajkummar said he "felt lucky to play the part". `Trapped` is slated to release on March 17.
