The TV show Gunsmoke ran from the mid 1950's to 1970's. If you were a big fan of that show and loved the character of Marshal Dillon, as played by James Arness, then you are going to love this TV movie from the 90's.
If you have no familiarity with the show Gunsmoke, and just come into this looking for a western TV movie, chances are, you won't be very impressed. Arness was almost 70 by the time this came out, and he was too old to be beating groups of guys in their 20's with fists and guns, but that was not the point of this film. The point was to give some old fans of an old TV show a taste of the past, and it does that job well.
