Maureen McCormick, who played Robert's oldest daughter Marcia on The Brady Bunch, has admitted that she had a huge crush on him while filming the show. She had no idea that he was gay until many years later. "I used to imagine running off with him!" McCormick has claimed.
Many of the young actors who played Robert's six children on The Brady Bunch recall how Robert was constantly quoting Shakespeare on set, so his character's philosophical ways were not all a matter of "acting."
