He was a fixture on lots of tv shows back in the day. Can't remember which ones though.
Looking through his filmography, I realized that other than Enter the Dragon, I had seen virtually none of his films. TV credits, though... Gunsmoke, Bonanza, Ironside, The Virginian, It Takes a Thief, Kung Fu, The Streets of San Francisco, The Rookies, Police Story, The Mary Tyler Moore Show, The Six Million Dollar Man, The Bionic Woman, The Rockford Files, Hawaii Five-O, Wonder Woman, Starsky and Hutch, Quincy, Fantasy Island, Vega$, Dynasty, Falcon Crest, Hardcastle and McCormick, Scarecrow and Mrs. King, Murder, She Wrote, The A-Team, Magnum P.I., etc. That's just a sampling, mainly of shows I was familiar with growing up then.
