In 1980, he portrayed Abraham Lincoln's Secretary of War Edwin Stanton in the television film The Ordeal of Dr. Mudd.

The scene where his L.A. Law character, Leland, the patriarchal and stiff founder of a successful law practice, was revealed to be in bed with competitor Rosalind Shays was ranked as the 38th greatest moment in television in an issue of EGG magazine. He earned one Emmy Award, and three more nominations, for his role as McKenzie on L.A. Law.
