Legends of the Superheroes is an umbrella title for two 60-minute live-action television specials produced by Hanna-Barbera Productions that aired on NBC on January 18 and 25, 1979.
The series was loosely based on Hanna-Barbera's Super Friends animated series, then airing on Saturday mornings on ABC; it served as a reunion of sorts for the 1960s' Batman TV series, as it brings back together three of its stars reprising their respective roles.
The specials were produced like standard variety shows of the time: on videotape and with a laugh track.[1]
