For those of you who aren't familiar with Tom's work, I'm including his resume below. He also has a page on imdb http://www.imdb.com/name/nm0642582/
From 1998 to 2006 he did around 30 shows in the various LAW & ORDER series. In the original LAW & ORDER, he was lawyer Peter Behrens for about 7 or 8 shows. Then he did many L&O SVU's as Judge Mark Seligman. He was in AMERICAN GANGSTER, UNITED 93, MAID IN MANHATTAN. And so many people always remembered him from the soap opera THE GUIDING LIGHT where he played Justin Marler.
