According to Indian media sources Aamir Khan, along with his wife Kiran Rao and son Azad Rao Khan were spotted at Mumbai Airport, ready to depart to Chicago, USA.

Sources added that Chicago shooting schedule covers the entire climax. The film's climax sees a supreme, fist-to-fist, man-to-woman fight between Khan and Katrina Kaif in what promises to be a one-of-its-kind fight between two powerful opponents.

The shooting will end up in three months and Khan will be back in India by the end of October in order to join the promotional campaigns of his upcoming movie “Talaash”.

Dhoom 3 is the third instalment in Yash Raj’s Dhoom franchise. The leading cast features Abhishek Bachchan, Uday Chopra, Aamir Khan and Katrina Kaif.

The movie is expected to be released sometime in 2013.
