Regarding Walter Matthau's deputy Harry.
It was played by William Schallert who did a great job in it. He had a great career as a character actor but it is strange that this great role didn't help him become an even bigger star.
It certainly helped in developing some stars such as the truck driver (Carroll O' Connor), the cruel deputy (George Kennedy), and of course Walter Matthauu the sherriff). Matthau and Kennedy were later to win oscars and O'Connor was to be great as Archie Bunker and in In the Heat of the Night tv series. Also Bill Bixby who was an uncredited helicopter airman who became famous as the father in The Courthship of Eddie's Father in the tv series.
