Susan Olsen wasn’t always a blonde. She had to bleach her hair regularly upon the producers’ orders. However, after a few seasons, her baby hair was noticeable as they appeared in giant clumps. The production staff had no choice but to leave her hair alone.

For the finale of The Brady Bunch, Robert Reed was completely written out of the episode. This was after his continuous disagreements with Sherwood Schwartz regarding the show’s plotlines. Reed considered the writing to be absurd. However, during the filming of the last episode, Reed stayed on set to be right by the kids’ side.
