I think to get into bollywood you just need to be hot, and know the right people, acting ability doesn't seem that greatly rewarded 
Priyanka Chopra is the most attractive woman on this planet.
I 100% agree with you. Although, Abhishekh Bachan got in, because of his father, and Esha Deol because of her mother. In most cases its a family heritage thing, if you look at Hrithik's father, was also an actor and director, and so was Kareena's Dad. However many of them drop out because IT DAWNS ON THEM that they suck at acting ....(Esha Deol- Have you seen her in 'Na tum Jaano Na Hum'? I practically switched it off after 15 mins, and Karishma Kapoor even though she is so pretty ....she's only done like 3 movies, the best of which I can think of is Dil To Pagal Hai.).
Rani, on the other hand, did not get selected because of her looks, but because she could dance and act pretty well. Surprising huh? It adds the the fact that she is gorgeous.
Priyanka Chopra, yea she is hot. But as I said before, cant act....see Aitraaz, and then you will believe me. Personally, the prettiest girls, would have to be Preity Zinta, Kareena Kapoor (not the skinny stick she has become), Madhuri Dixit, Ashwariya Rai and I quite like Deepika Pandukone (sp?).
Isn't being pretty like the first criteria in most international films? I've seen Korean dramas, that have some pretty skinny, but pretty chicks.
Apparently Dhoom 3 is coming out.....with Aamir as the villian. sounds good:)
