He was in Return of the Gunfighter (1967, billed as "Read" Morgan), starring Robert Taylor. Red played the brother of Michael Pate and Henry Wills. I think Red doubled almost everyone in the film! he could be clearly see doubling Pate, John Crawford (as Butch cassidy), and possibly Taylor and Lyle Bettger, but Taylor looked like he did most his own.
CORRECTION: I'm wrong on this, because I see Read Morgan has totally different credits in IMDB. Weird tho, because he's a dead ringer for Red.
