It seems that the third installment of Dhoom may not have Aamir Khan as the good cop after all.
Rumour mills were working hard when Aamir was touted for the role, replacing Abhishek Bachchan, but Aamir has turned down the project. The reasons for this are unclear, but Aamir was not happy with the good guy role, as in the Dhoom films it is the baddies that win all the accolades.
So now it is a change of plan for the film’s director Aditya Chopra, who has decided to direct the film himself, and he has roped in another Khan; Saif Ali Khan.
Saif will now play the role initially written for Shah Rukh Khan, and Shah Rukh Khan will be the cop, replacing Aamir Khan. Not only that, but Zayed Khan is to replace Uday Chopra, who will be seen in the film albeit a special appearance.

this combination is not new to us ,we have seen both khans in kal ho na ho! But why is shah playing the cop isnt it the baddie who has the meatier role in dhoom flicks?
ye kya hai.
HEY IT WAS WAS SUPPOSED SHAHRUKH 2 PLAY THE VILLAIN!!
SRK + SAIF + ZAYED = DOOOMED 3
SRK WINNING WORST COP - BODY LIKE DRIED SHRIMP IN OSO
SAIF WINNING WORST BADDIED - DIALOGUES LIKE — SRK TERI MAAAAA ( JUST LIKE IN OMKARA)
ZAYED - GOD KNOWS WHEN AND WHY HE BECAME AN ACTOR
I hope that is true >>> Saif & SRK = SUPER HIT MOVIE
