This was the only Brady show in sitcom form to be filmed in front of a live studio audience.
Although billed as a guest star, Florence Henderson was essentially a regular, appearing in all but one episode of the short-lived series.
Years later Maureen McCormick would admit to having a terrible cocaine problem during the entire run of the series.
Barry Williams and Christopher Knight and Susan Olsen and Mike Lookinland decline to return in this new series to reprise there roles as Greg Brady and Peter Brady and Cindy Brady and Bobby Brady because they were not interested in reprising there roles in this series because they wanted to break away from there characters and avoid being typecast as there characters forever and they wanted to do other projects and roles to avoid being typecast but they enjoyed doing the original Brady bunch series it's just they were not interested in reprising there roles in this new series because they wanted to move on from the roles and avoid being typecast and they wanted to do other projects and roles.
The show was canceled after one season because of low ratings because many fans felt the chemistry and charm were missing without Greg Bobby and Cindy and Peter since it only focused on Marcia and Jan with their new husbands so the show was canceled after one season because of low ratings because of all that stuff.
