About R. G. Armstrong
Robert Golden Armstrong Jr. was an American character actor and playwright. A veteran performer who appeared in dozens of Westerns during his 40-year career, he may be best remembered for his work with director Sam Peckinpah. Armstrong's first film appearance was in the 1954 film Garden of Eden; however, it was television where he first earned a name for himself. In 1991, Armstrong portrayed the title character in the music video for "Enter Sandman" from heavy metal band Metallica, which won the 1992 MTV Video Music award for best metal/hard rock video. Even outside of Peckinpah's work, Armstrong became a tier-one character actor in his own right, appearing in dozens of films over his career, playing both villains and sympathetic characters.
