John Wayne played US Marshall Rooster Cogburn helping a cute teenage girl (Kim Darby) look for the man who killed her father.
The cast is rather interesting: Country singer Glen Campbell, Robert Duvall and Dennis Hopper. This is Duvall a couple of years before he played Tom Hagen in "The Godfather".
Wayne won his only Academy for this movie.
