• Blue River (1995): Henry Howland. The page lists it twice, as a film and a TV film, and doesn’t give the genre.
• The Yellow Rose (1982): Chance McKenzie. It’s a modern-day Texas ranch drama series.
• Ghost Rider (2007): Carter Slade / Phantom Rider. It’s a superhero film with a western-flavored backstory.
• Texarkana (1998): a TV film with his role listed as “N/A.” I can’t tell the genre or role from this page.
