Wonder Woman Meets Mr. America - Roger Callard & Lynda Carter 1978
1970s Bodybuilding Legend Roger Callard has a long list of professional TV & movie credits including this role as "Bill" in the "Screaming Javelins" episode of the Wonder Woman CBS TV show. This episode aired in January 1978, so it was probably filmed in 1977 between Roger's class wins at the 1977 Mr. America and the 1978 Mr. International.
