Concerning Michael Wilmington’s “Cowboys and Indians With a Conscience” (Dec. 16), check out “Devil’s Doorway” (1950), starring Robert Taylor and directed by Anthony Mann. It’s about an Indian coping with prejudice after serving in the Civil War and it’s stronger than “Broken Arrow” of the same year. Taylor was strangely cast, yet he is surprisingly effective. Probably his best-acted role. The film is neglected, but well worth a look.
