Hrithik is married as far as I know but if you are asking for his filmy pair then I will suggest Katerina Kaif. They haven't been together in any movie but I have the feeling they will look good if they come together.
I also think that Katrina Kaif would be good for Hrithik. Am waiting to see them together in a movie. - Mr.President -
The entire hindi movie industry reeks of nepotism. People with mom and dad or an uncle in the industry gets most of the breaks. And this could be one reason why they do not make movies like they used to in old days. Most of the actresses have a few sets of expressions that they cycle through randomly or in que during a movie. Same can be said of the male casts. People who have variety in acting and real talent are wasted without good directors and suffer due to poor execution of plots and scripts. You will find only the star kids being regularly featured in movies or getting breaks. Example 1. Uday Chopra (A wooden monkey with fixed facial expression, a goofy grin, a stocky body and plenty of moolah and connections) 2. Hrithik Roshan (Ham handed acting and poor man's pierce brosnan. Tries to imitate sean connery consciously or unconsciously) 3. Tushaar Kapoor (The less said, the better it is) And the list could go on. Seriously they should start professional casting to choose leads and other role actors for most movies and stop making dopey masala crap that they dish out every friday.
You are absolutely right about these two guys. But Hrithik is different. He is the best dancer in Indian film industry and no doubt he is the most handsome actor. Its just that he has to improve on his acting skills. Do you remember Abhishek was also a crap actor when he started but he has improved in the course of time just watch Delhi 6.
I would also vote for Katrina Kaif, as she is kinda Actrress who fits with almost everybody and m sure she would fit with Hrithik as well.
