For The Win
Mike and Carol Brady were cast after their six children were cast! It seemed a bit in reverse to cast the parents last, but the backwards nature of the casting worked, and the show was a hit after syndication.
The D Word
At the time of airing, it was more culturally acceptable for Florence Henderson to joke that she killed her husband than what the producers originally wanted her to say: that she got a divorce! The network rejected all hints of a divorce from the writers, so Mike was a widowed man and Carol’s background was swept under the rug during the show.
