Direct contact information, as in his home 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, you wouldn't get an answer.
This is what fanmail is for if you just want to say hi. Fanmail addresses can change, so if you 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 you are more likely to gain an honest answer)
However, if you want to contact him for business reasons, then you will have to contact his agent (which I think you can find on imdbPro, but unfortunately you have to be an imdb subscriber to get that info)
