Kevin Costner and Clint Eastwood both received Best Director Oscars in the years shortly preceding this film. Both of their respective films ( Dances with Wolves (1990) and Unforgiven (1992) ) were westerns. Consequently, this marks perhaps the only time in film history when two such Oscar-winning directors co-starred as actors in the same film. (Also: see Chinatown (1974) Trivia.)
Early in the movie, references are made to President John F. Kennedy visiting Texas and the governor running for re-election. Unless the events in the movie take place in an alternate universe, this was not JFK's final, fateful trip to Texas. From 1876 to 1972 Texas governors served two year terms, which means this movie took place prior to the November 1962 election. JFK was assassinated in Dallas a year later in November 1963.
