I thought I had posted this earlier in the thread, but I don't see it--I had read last year that the reason he was doing that TV show (which I have not seen) was because he needed the steady income; apparently his divorces had cost him a lot and he had been forced to downsize his residence (i.e., sell his ranch/estate/whatever and move to smaller digs).
It's funny how here's a guy universally acclaimed for his talent, been in umpteen successful movies, you would normally expect him to have more money than he knew what to do with. I don't know whether that's a lesson in how being talented and successful doesn't necessarily make you smart with money or insulate you from the vagaries of life (or addiction), or whether it's a lesson in how precarious all of our existences are.
