Rio Bravo is viewed as one of the most influential Westerns of all time and a highlight of John Wayne’s legendary career, but some fans might not realize it is part of a trilogy from the actor. Wayne is mostly linked to the Western genre and appeared in some of the most iconic films in the genre, including True Grit, The Searchers, Red River and The Cowboys. Even with the decline in popularity of the Western, he was making movies in the genre right until the end of his career, with his last movie being 1976’s The Shootist.
