Mumbai, Nov 29 (PTI): Actor Aamir Khan, who is playing a baddie in 'Dhoom 3', feels that changing moral values in society have blurred the line demarcating the good and evil on screen.

After success of 'Dhoom' (2004) and 'Dhoom 2' (2006), there is already a buzz going around about the third edition of the series. In the upcoming instalment of 'Dhoom' factory, Aamir is playing a negative character opposite Katrina Kaif.

"I think villains have moved out of our scenarios. We don't have any villains anymore in our scripts by and large. It's more of a social thing. At one time our society had a clear moral view. So those people were the villains in our stories too. Mill owners were the villains," Aamir told PTI.

The actor says the profile of villains on screen has undergone a sea change over years and they are no more in-your-face baddies.

".....Then it was smugglers, underworld, politicians. So society looked upon a certain section and said that we don't like these people. Today, we don't have such strong moral concepts.

Being clever and opportunist is not a bad thing anymore. We don't have black and white views and moralities," he opined.

'Dhoom' series revolves around daredevil thefts, their cupid protagonists and thrilling bike chase.

Actors Abhishek Bachchan and Uday Chopra will reprise their roles as Jai and Ali in the third instalment as well.
