Direct contact information, as in his প্রথমপাতা address? I highly doubt he would allow that information to get onto the internet. Even if it did and anyone attempted to contact him with it, আপনি wouldn't get an answer.
This is what fanmail is for if আপনি just want to say hi. Fanmail addresses can change, so if আপনি find one that people say is valid, actually make sure it is. Check how old it is and if people have actually gained a response (of course some people do lie, so I'd say the best place to get that information is from actual fansites where আপনি are আরো likely to gain an honest answer)
However, if আপনি want to contact him for business reasons, then আপনি will have to contact his agent (which I think আপনি can find on imdbPro, but unfortunately আপনি have to be an আইএমডিবি subscriber to get that info)
