Rajkummar Rao in Mental Hai Kya

Two days into the shoot of Mental Hai Kya, Rajkummar Rao is upbeat about the thriller that sees him reuniting with his Queen (2014) co-star Kangana Ranaut. Though pictures of Ranaut shooting a sequence in pyjamas have made the rounds of the Internet, Rao refuses to divulge details about the Prakash Kovelamudi-directed project — all he is willing to say is that it's "a tough part to play."
