"There is a certain amount of mystery about Emraan. As a person, there is a sense of enigma around him, you can never make out what he is thinking. He speaks less. Also you don't know whether to believe him or not. He fits the character of Sanjay Athray well," Gupta told PTI in an interview.
The comedy-thriller also stars Vidya Balan, who plays Hashmi's over-the-top Punjabi wife in the film. This is Gupta's second collaboration with the National Award-winning actress. They have previously worked in 2011 hit film "No One Killed Jessica", which was based on the controversial Jessica Lal murder case.
"Ghanchakkar" is Gupta's third film. He made his Bollywood debut in 2008 with critically and commercially successful film "Aamir" and then followed it up with "No One Killed Jessica".
"'Ghanchakkar' is a very different movie from my previous films. It is in the humorous, suspense, thriller space that I have not explored before. We don't make comic thrillers - it is either a comedy or a thriller.
"Ghanchakkar" also stars Rajesh Sharma and Namit Das and will hit theatres this Friday.
