The stars they are actually considering to rope in for their film are Oscar winner Natalie Portman, Spanish superstar Penelope Cruz and Eva Longoria of Desperate Housewives fame.
Confirming the buzz to a leading daily, a source said, "The names you mention are definitely in the list. Yashraj has never worked with an international star in any of its films.
The production house has now decided to take the ‘Dhoom' franchise to a global level. One safe and effective way of going global would be the casting of a Hollywood hottie.
The role will involve sporting swimwear and a passionate kissing scene with Aamir; the parts that Katrina had problems with and thus failed to land the dream role. "
When contacted, Yashraj's official spokesperson also confirmed the news and said, "Yes, as of now some new international options are being considered."
