Is there is a possibility of buying the domains and selling them later to the actors? Or can we park them with ads?
Practically any question of the form "Is it okay to make money off of someone else's name and reputation?" is not going to have a happy answer.
Just get a nice Bollywood or Hollywood related domain, and then promote it.
Considering how the ultimate answer above comes from a reputable IP attorney, I suggest you take it as gospel. Plus, it's free.
