They had 3 girls on the left, 3 boys on the right with Mike and Carol in the middle, and Alice in the center. The 1988 reunion moviehad a grid of 16 people that included the inlaws, grandkids and original cast.
In the movie "The Brady Girls Get Married" in 1981 Cindy enters college as a freshman. This movie is filmed in 1988. That means Cindy would have been in college for 7 years.
It it strange that Bobby and Cindy to be still in college. It is 1988 and they should be in their late twenties and their careers just started.
There is another bathroom revealed in this reunion movie by the den. In the original series they were upstairs. Apparently Mike and Carol had the house remodeled after all the kids left.
The opening credits has the original theme song with the Brady kids singing, and the cast photos from the first season and changes to the adult kids and older Carol, Mike, and Alice photos with the Christmas decoration around.
In real life, Maureen McCormick (Marcia Brady) was pregnant during the filming of this movie. Later that year, in May 1989, she gave birth to her daughter Natalie.
When Carol gives the woman the check, she has a bracelet, but in the later when Carol says, "Told you i was Mrs. Mike Brady", the braclet's gone.
Mike: What do you think, Alice? Greece or Japan?
Carol: Japan or Greece?
Alice: Can I skip that question and go right to the bonus round?
Allan Melvin guest stars as Sam in the series, but he does not appear in this Christmas reunion movie. Lewis Arquette plays Sam in this reunion movie.
This was the highest rated Christmas movie made for television.
Susan Olsen (Cindy Brady) was the only original cast member who did not appear in this movie. She was honeymooning with her husband in Jamaica at the time. Additionally, the actress backed out because with the film's limited budget, she was to be paid less than the others. So Jennifer Runyon was tapped to play Cindy.
Jonathan Taylor Thomas later played Kevin Brady in "The Bradys."
The lady Carol talks to at the Travel Agency later appears in "The Brady Bunch Movie" as one of the Brady's neighbors gathered on the street.
