In the Coen Brother's film The Big Lebowski, The Stranger (played by Sam Elliott) is the narrator of the film.  He appears at the beginning, middle, and end, and even speaks with The Dude at the bowling alley bar while sipping on a sarsaparilla.  The Stranger is dressed like a relatively run-of-the-mill cowboy, but Sam Elliott's trademark mustache really helps solidify the character as something special.
