Timothy S. Guinee is an American stage, television, and feature-film actor. Primarily known for his roles as Tomin in the television series Stargate SG-1 (1997–2007) and railroad entrepreneur Collis Huntington in Hell on Wheels (2011–2016), he appeared in the Marvel Cinematic Universe (MCU) feature films Iron Man (2008) and Iron Man 2 (2010) as United States Air Force Major Allen, and as struggling father and retired major Clay Wilson in the first season of the streaming television series The Punisher (2017–2019).

Collis Potter Huntington was an American industrialist and railway magnate. He was one of the Big Four of western railroading who invested in Theodore Judah's idea to build the Central Pacific Railroad as part of the first U.S. transcontinental railroad. Huntington helped lead and develop other major interstate lines, such as the Southern Pacific Railroad and the Chesapeake & Ohio Railway (C&O), which he was recruited to help complete. The C&O, completed in 1873, fulfilled a long-held dream of Virginians of a rail link from the James River at Richmond to the Ohio River Valley. The new railroad facilities adjacent to the river there resulted in expansion of the former small town of Guyandotte, West Virginia into part of a new city which was named Huntington in his honor.
