Dr. Cox mentors the rookie doctors with a spoonful of dirt and then a cup of sugar. I see him as an archetypal descendent of two of my favorite curmudgeonly characters: Lou Grant and Louie De Palma.

In 2007 he had a role as Chuck in the film Are We Done Yet?. He has also done commercials for the Champions Tour a professional golf tour for men over the age of 50. McGinley had been cast in his first film role in Alan Alda's Sweet Liberty earlier in 1986.

Apart from acting McGinley is also an author and a spokesperson for the National Down Syndrome Society. He has also written and produced for television and film. John Christopher McGinley (born August 3 1959) is an American actor.
