One of my favorite non-Duke westerns is Man Without A Star.  I think it's been released in Europe, possibly, but not in North America.  It stars Kirk Douglas who even gets to sing and play the banjo in this movie.  A very lively film.  Claire Trevor is in this, too, I think.  This is the only movie off the top of my head I can think of.  Of course, if we went to TV series, I could name Lawman and How The West Was Won and a whole bunch of others...
