6. Willie Nelson ('El Viejo,' Season Three)
The red headed stranger played a rogue former Texas Ranger who shows up mysteriously at a drug bust and makes away with a briefcase full of cash. His character, Jake Pierson, later redeems himself by helping Crockett and Tubbs take down a Bolivian kingpin, taking a bullet in the process. Nelson was an acting pro by this time, having already appeared in Sydney Pollack's The Electric Horseman (1979), the semi-autobiographical Honeysuckle Rose and alongside Gary Busey in the Western Barbarosa (1982). As we wrote in our countdown of Willie's greatest acting roles: "Ever the cowboy, he shuffles off Miami's mortal coil in a death scene worthy of Shane."
