Trivia

Frequently walked off the set of The Brady Bunch (1969), due to arguments with series creator/producer Sherwood Schwartz. In addition, he sent voluminous memos to Schwartz, detailing his unhappiness with the writing and directing on the show. Schwartz put up with this only because Reed's instincts usually turned out to be right. (Reed would eventually direct a handful of episodes himself.)

He kept his illness from the rest of the The Brady Bunch (1969) cast for years. He finally contacted Florence Henderson days before his death and requested that she inform the rest of the cast of his condition.

He grew up with his parents on a farm where they raised cattle and turkeys.

In one of his last interviews, he revealed that he actually detested The Brady Bunch (1969) and that his role as Mike Brady embarrassed him.

Only cast member of The Brady Bunch (1969) to miss two episodes. The first was Goodbye, Alice, Hello (1972). He was written out of the second one, The Hair-Brained Scheme (1974), because he strongly disapproved of the script, which had Greg's hair turning orange because of a cheap hair tonic.

Replaced Robert Redford on Broadway in Neil Simon's "Barefoot in the Park."

In 1991 with his health declining, he appeared on Sally Jessy Raphael (1983) celebrating Father's Day, TV Dads (1991), with among other TV Dads Conrad Bain and John Astin. While on the panel, he spoke about the evils of putting children on television shows.

The epitaph on his tombstone reads: "Good Night, Sweet Prince." This is taken from the final line of William Shakespeare's "Hamlet".

His Shakespearean background included roles in "Romeo and Juliet" and "A Midsummer Night's Dream" as part of an off-Broadway company called "The Shakespearewrights." Toward the end of his life he taught a course in Shakespearean acting at UCLA.

Transferred to the Royal Academy of Dramatic Arts in London, England, UK.

Attended Northwestern University (Evanston, Illinois).

He was cremated and his remains buried at the Memorial Park Cemetery in Skokie, Illinois at a later date.

Member of Beta Theta Pi Fraternity.

Was the only child of John Robert Rietz Sr. (1912-1975) and Helen Teaverbaugh Rietz (1913-2002).
