Wonder Woman aka The New Adventures of Wonder Woman first came to TV with a trio of films consisting of a pilot (November, 1975) and two one-hour specials (April, 1976). The series began airing steadily by December ’76.
The show starred Lynda Carter as Wonder Woman and Lyle Waggoner as Major Trevor. Guest stars were too numerous to mention, nevertheless, I’ll throw in the names Leif Garret, Roddy McDowall, Rick Springfield, Ed Begley Jr. and Debra Winger. View the Wonder Woman intro from season three below.
