DHOOM 2(back in action)

Dhoom 2 was filmed in Mumbai, India, Namibia, Durban, South Africa, and Rio de Janeiro, Brazil,[25][26] making it the first Bollywood film to be filmed in Brazil.[3] Air travel from India to South Africa was sponsored by Kingfisher Airlines.[27] In total, production lasted eighteen months and cost of Rs 350 million.[1][28] To ensure the sequel would be different from the original, which became famous for its brash motorcycle stunts, director Sanjay Gadhvi did not include motorcycles in Dhoom 2.[29] Nonetheless, Roshan's role required him to perform several dangerous stunts involving activities such as roller-blading, sand boarding and snow boarding.[30]
The film made extensive use of visual effects, which were filmed at Yash Raj Studios.[3] While filming at Yash Raj Studios, the film suffered from a flood that destroyed the studio sets and delayed production.[3] Fight and action sequences were storyboarded before being shown to Gadhvi and Allan Amin, who would make changes. The scenes were then sketched, given "proper shot list[s]", and shared with Tata Elxsi, who oversaw the previsualization of the sequences.[31] Several scenes were filmed with the use of green screen and computer-generated imagery.[31] For example, the stunts Roshan's performed on a train in the Namib Desert used green screen; after Roshan recorded the stunts on a set, Gadhvi traveled to the desert to film the background.[31] Other stunts in the film were performed by stuntmen whose faces were later digitally exchanged with the actors'. The bullet effects and Hrithik's gadgets and mechanical arm were also computer generated.[31] Abhishek Bachchan scene coming out of a lake using a jet ski also used green screen. Abhishek's stunt came out of 90 degrees, but Sanjay Gandhvi wanted a 60 degrees jump.[31] So, Sanjay Gandhvi shot the scenes on Super 35, and was able to change the angle.[31] Gandhvi discussed the use of technology in an interview;
“
We've done animation and pre-visualization for all the action sequences in Dhoom 2 and that is very important in terms of planning, cost effectiveness and also it's a new way of preparing for shoot and the film specially which is as set on such a large canvas such as Dhoom 2. In Dhoom 1 we had all the action sequences broken down and written. In this movie we had very big action sequences so we had all the scenes storyboarded and they would be checked, double checked and triple checked by myself, Alan Amin and Adi and we would then rectify if needed and that would be our level of planning.[31]
