India Today says:
"Tabrett Bethell, Australian actress, has been signed up by Yash Raj Films as the other heroine in the much-hyped Dhoom sequel"
"Tabrett was reportedly approached for the role at the beginning of the year but the final contract was only signed last month. She will play a blonde living in the US and sparks fly when she meets Uday's character, Ali."
"'Her role will be somewhat similar to that of Bipasha Basu, who played the romantic interest of Uday in Dhoom 2,' said a source in the film's unit."
"Aamir takes over as the central baddie, playing a super thief who is a skilled acrobat. Aamir has already shot for some daring stunt sequences in the famous Chinatown area of the city"
"Tabrett will start the shoot in the coming week and already started preparations for her role. 'She will be given a team who will help her with the dialogues and some Bollywood style dancing,' a source said."
The film's big Bollywood stars are: Abhishek Bachchan, who plays the main character in the successful series, ACP Jai Dixit, a no nonsense cop; Amir Khan (playing the anti-hero; perhaps he's the biggest star, he talked to Rahm Emanuel, the mayor of Chicago - where the film is being shot now - to get necessary permissions quickly); Katrina Kaif (the female lead); Jackie Schroff; and of course Uday Chopra, as the other main character who appeared in the first two films, as Ali Akbar, a clownish downtown racer.
The interntaional cast includes Kim DeJesus and Paul D. Morgan.
Marking Tabrett's debut in the Hindi film industry, Dhoom 3 will be an action-thriller, to be released in 2013, in IMAX format.
