William Russ (born October 20, 1950) is an American actor.
Russ' acting first began on the New York stage before he embarked onto a television and film career. In 1977, he had his first supporting role in Death Bed: The Bed That Eats. This film would not be officially released until 2003.
During the 1980s, Russ found work in more supporting roles such as Crisis at Central High (1981), a television movie also starring Academy Award winning actress Joanne Woodward, The Border (1981), The Right Stuff (1983) as Slick Goodlin, St. Elsewhere (1986), Crime Story (1986), and Wiseguy. He continued finding work in both television and film. He also guest starred in the television series Miami Vice in the 1985 episode "Evan" as the title character, a ATF agent who shared a history with Don Johnson's character, Sonny Crockett.
Russ received critical acclaim when he starred in Pastime (1991) as Roy Dean Bream, a veteran minor league hurler who mentors a young phenomenon. The role earned him a nomination at the 1992 Independent Spirit Awards for "Best Male Lead."
In 1993, he was cast as Alan Matthews on the television sitcom Boy Meets World. Russ played this role until the series ended in 2000. However, he continued performing in other series and films throughout his time on Boy Meets World, primarily television movies. In 1998, he performed as Danny and Derek Vinyard's father in the critically acclaimed American History X. Later, he starred in the short-lived television serial drama Mister Sterling.
