"It is true that Emraan Hashmi is playing a Maharashtrian in 'Ghanchakkar'. It is interesting because I think he hasn't played one in his career. The film has been entirely shot in Mumbai," said Gupta.
The film is about a quirky marriage between a Maharashtrian man and a loud Punjabi housewife essayed by Vidya Balan.
"Vidya speaks Punjabi in the film, but you will have to wait to see how Emraan got the nuances of playing a Maharashtrian," said Gupta.
Emraan's character is called Sanjay Athray, born and brought up in Mumbai. He is shown to be a guy who has come up in life the hard way, someone who was a lock picker in his early days, but who now lives a respectable life.
"Ghanchakkar" will release June 28.
