Emraan Hashmi, who has had a slew of hits lately, believes his latest "Ghanchakkar" will be his biggest hit ever.

"There has been a huge change for me in the last 3-4 years with films like 'Once Upon A Time in Mumbaai' and 'The Dirty Picture' and, Inshallah, I feel the way 'Ghanchakkar' has been made and the feedback we have been getting from those who have seen the edit, I am very sure that this will be my biggest success," he said.

Emraan, 34, has had a string of successes like "The Dirty Picture", "Jannat 2", "Raaz 3D" and "Ek Thi Daayan".

"Ghanchakkar" is a comic thriller and tells the story of a Maharashtrian man who claims to have forgotten about the money he had hidden somewhere.

Talking about the film, Emraan said the film carries such suspense that no one will be able to guess who actually has the money.

"The film's theme is comic but there is a suspense angle to it. I assure you, when you will see the film, you will not be able to guess who actually has the money," Emraan said.

He credits the writers - Raj Kumar Gupta and Parvez Sheikh - for creating fine suspense in the film.

"The way the film has been written and treated, every 15 minutes you will feel that the protagonist is lying and his memory is fine and may be he has the money. Then you will think the wife has, and later you will even be suspicious about the other two men. But you will never be able to guess what will happen in the climax and who has the money," he said.

Directed by Gupta, "Ghanchakkar" stars Vidya Balan opposite Emraan as his loud Punjabi wife and hits theatres June 28.
