Aamir, 49, who recently watched the trailer of the action film, said Hrithik and female lead Katrina kaif are looking like "million bucks".
"I wish I could dance half as well as Hrithik! I really loved the new song of 'Bang Bang'. And the Bang Bang trailer is outstanding! Hrithik and Katrina look like a million bucks!," Aamir posted on twitter.
Hrithik unveiled the film's first romantic track 'Tu Meri' last month where the lead pairs could be seen doing some high-octane dance moves.
The 'Dhoom 3' star is also amazed by the action scenes of the action-romance film.
Produced by Fox Star Studios, 'Bang Bang' is directed by Siddharth Anand. It will hit theatres along with Vishal Bhardwaj's 'Haider' on October 2.
