He’s not sick. Nor is he really weird looking, I don’t think. He is preparing for a role in the upcoming movie, Maverick’s, where he is playing Rick Hesson, mentor to surfer Jay Moriarty. And right before that, he was filming Playing the Field, where he plays a soccer coach, and we often saw him being active in the behind the scenes photos. I would assume that his new “skinny” physique (I would classify it more as toned down - he’s always been quite tall and lanky in his younger years) is from that, as compared to being sickly, as some people throw around.
Also, no need to be anon! :)
