The Red, White, and Black

Surprisingly, though its packaging might make you think this is an exploitation movie, this western (concerning the real-life Buffalo Soldiers) actually takes itself very seriously, despite instances concerning action and sex. Though the movie had serious intentions, it feels like it was made by exploitation filmmakers, and the movie still has a weird feeling of exploitation to it (possibly due to the low production values.) It isn't very compelling, but it may have enough curiosity value for fans of drive-in movies of the time.
