Talking about it, Rajkummar told IANS: "I am doing a special appearance in the film. Bhatt sir (Mahesh Bhatt) really wanted me to play this part and I love him too much, can't say 'no' to him.

"It's a really challenging part for me, so that's also the reason I thought I should do this special appearance because it's going to challenge me as an actor."

"Humari Adhuri Kahaani" stars Vidya Balan and Emraan Hashmi, and it is directed by Mohit Suri.

The National Award winner says he is "looking forward" to work with the team.
