Williams played Britt Reid, the editor and publisher of The Daily Sentinel who battled crime as the masked Green Hornet. Reid had to dodge both hoods and the police, who believed the Hornet was a racketeer.
The district attorney, Frank Scanlon (Walter Brooke) was in on the masquerade. Meanwhile, Sentinel reporter Mike Axford (Lloyd Gough) was determined the Hornet be captured.
The show, however, became a platform for Bruce Lee, who played the Hornet’s assistant, Kato. Lee’s skill in martial arts was a highlight of the series. For youngsters in the audience, Lee’s Kato upstaged Williams’ Green Hornet. Lee (1940-1973) would become a star before his sudden death.
The show, based on a radio series, was an attempt by producer William Dozier to extend his success with masked characters after the debut of Batman in January 1966. Dozier even provided the narration in the show’s main titles, using his “Desmond Doomsday” voice he utilized in Batman.
Dozier’s Batman series also featured a two-part story in 1967 where the Green Hornet traveled to Gotham City, running afoul of Batman. Earlier in that same season, Bruce Wayne (Adam West) and Dick Grayson were briefly depicted watching The Green Hornet on television. In a different episode, the Green Hornet and Kato opened a window and talking to Batman and Robin, who were climbing up a building. Robin (Burt Ward) commented about the strange outfits worn by The Green Hornet and Kato.
Earlier in his career, Williams played private detective Kenny Madison, first on Bourbon Street Beat (1959-60) and then Surfside 6 (1960-62). two Warner Bros. series that aired on ABC.
