Chennai, Dec 18 (IANS): Writer-director Vijay Krishna Acharya promises high-octane action in "Dhoom 3", which releases Friday, but he said that the stunts in the film were made with a degree of credibility.

"The 'Dhoom' franchise is known for its action and the expectations we had as the makers was to up the ante. While the action in the film is fairly spectacular, at the same time it has been made with a sense of believability for the world of viewers," Acharya told reporters here Tuesday.

The film is already being lauded for the stunts featured in the trailer and especially the bike scenes featuring Aamir Khan.

"We did the India action with our Indian action director but most of the action sequences were done in Chicago and that was handled by Hollywood stunt man Conrad Palmisano. The entire stunt team was from LA because we needed professionals," he added.

Acharya had penned the story for the first two parts in the franchise.

Aamir Khan and Katrina Kaif are the new entrants to the "Dhoom" franchise, which also features Abhishek Bachchan and Ali Akbar in important roles.
