In an effort to make viewers tune in to both 'Bionic' series, the The Six Million Dollar Man (1974) season 4 premiere, The Return of Bigfoot: Part 1 (1976) continues over to The Bionic Woman (1976) season 2 premiere The Return of Bigfoot: Part 2 (1976). However, in syndication these two episodes are shown as part of The Six Million Dollar Man (1974) series.
This is the first time that Col. Austin is seen with a mustache.
Ted Cassidy replaced André René Roussimoff as Bigfoot. Both actors would eventually pass away at the same age (46), but in different years. Both would also pass away from heart related issues.
John Saxon (Nedlick) previously played Maj. Frederick Sloan (and his robot double) in "Day of the Robot" (S1 E4)
This is the first episode to show the new opening credits sequence. With this sequence, we now have a different shot of Richard Anderson and Martin E. Brooks has been added as a permanent cast member. Also the theme music has a slightly faster tempo.
