An actor, known for Thirteen Days (2000) as Robert F. Kennedy, JAG (1995) as CIA Agent Clayton Webb and Desperate Housewives (2004) as Rex Van de Kamp.

Despite being killed-off in season 1, Rex has appeared since in every season (excluding season 4 and 6). During the 2003-04 television season, the hardworking Culp successfully juggled recurring roles on an unheard of four series at one time: on CBS's JAG (1995) (as CIA Agent Clayton Webb), NBC's The West Wing (1999) (as GOP Speaker of the House Jeff Haffley), NBC's long-running hospital drama ER (1994) (as schoolteacher Dave Spencer), and on UPN's futuristic series Star Trek: Enterprise (2001) (as MACO commander Major Hayes). He also managed to squeeze in guest spots on The Lyon's Den (2003) and CSI: Crime Scene Investigation (2000).
