Robert Patrick (born November 5, 1958 in Marietta, Georgia, USA) is an American actor. He was a track and field and American football athlete at Bowling Green State University.
He is the brother of Filter lead singer Richard Patrick. He is married to actress Barbara Patrick who appeared with him in some of his films such as Zero Tolerance and as Barbara Doggett in two episodes of The X-Files. He has a daughter (Austin) and a son (Samuel). Almost every year, he does the Love Ride, an annual motorbike race that raises money for charities.
Patrick shot to fame by starring opposite Arnold Schwarzenegger in 1991's Terminator 2: Judgment Day. He played the T-1000, a Terminator that assumed human form but was made of a substance that could imitate anything it touched; his character fought against Schwarzenegger's now 'good' T-800.
