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