New Delhi, Oct 6 (IANS): Actors Irrfan Khan and Aishwarya Rai Bachchan who are starring in Sanjay Gupta's "Jazbaa", say the film "is a roller coaster ride" and they did not find anything difficult or challenging in portraying their characters on-screen.

"There was no difficulty in this movie. There was always fun and excitement...'Jazbaa' is not a film where you are deciphering a role or trying to understand somebody by going into the psyche of the character", Irrfan, who is essaying the role of a suspended police officer in "Jazbaa", told IANS at a press conference, while promoting the film here.

"This movie is out-and-out roller coaster ride and there was no challenge," he added.

The actor, who also portrayed the role of an investigating officer in Meghana Gulzar's "Talvar", based on the 2008 murder of 14-year-old Aarushi Talwar and her family's domestic servant Hemraj, praised Sanjay's distinct style of filmmaking.

"Sanjay Gupta has a particular style, I am coming from a different way of working so when two different types of projects come together they create dynamics...given the fact that if you believe in 'do kadam tum chalo aur do kadam hum chalein' (you walk two steps and I walk two steps) then the picture comes out right. It was his (Gupta's) dynamics and my way of working...it was always fun," he said.

The film, which also marks Aishwarya Rai Bachchan's return to the silver screen after a gap of five years, sees the "Devdas" actress portraying the role of a lawyer.

"I am a working mother, so by vocation I am a lawyer (in the film). The director has done all the research that needs to be done before presenting to the actor and it is not that its taken from reality so that you really need to match the certain kind of fact," Aishwarya said.

Irrfan, who has come to the country for two days from Lithuania just for dubbing for "Jazbaa", also added that the only thing that was "tough" in the film was the "location".

"The location was so tough, it was difficult to reach it. Reaching there was an achievement in itself," the "Jurassic World" actor quipped.

The film, which also features Shabana Azmi, Chandan Roy Sanyal and Jackie Shroff is a Hindi remake of South Korean movie "Seven Days".

"Jazbaa" is produced by Essel Vision, White Feather Films and Viking Entertainment and is slated to hit the theatres on Friday.
