For the first time, the 
Mary Martin "
Peter Pan" is presented as a stand-alone two-hour special on 
NBC instead of as part of an anthology series. This version, rather than being presented live, is shown on videotape, enabling 
NBC to repeat it as often as they wish without having to restage it. Although nearly all of the adult actors repeat their original 
Broadway roles, all of the original children have, ironically, outgrown their roles and are replaced by new actors.
