From the Viggo-Works forum:
The USA Biography Channel ran this program 3 or 4 months ago. The name of the show is called Famous and they show 2 half hour episodes featuring 2 different actors. It's usually on Sunday mornings 7-8 ET.
It isn't really a Biography of their lives, but is more about their movies. It featured several old interviews with Viggo talking about his films, including, American Yakuza and The Prophecy. Needless to say, he was gorgeous!
The episode of Famous with Viggo Mortensen is scheduled for Sunday, March 22nd at 7 a.m. ET on the Biography channel. Check your local listings for times in your area. And enjoy!
p.s. Just noticed that following Viggo's 1/2 hour, at 7:30 a.m., is Clive Owen! A great two-fer. :)
