Unless of course, you count that made for TV movie from 2002 about the Mike and Carol becoming the President and Vice President of the United States.

I guess the most logical step in terms of material to mine would be the various after-show spin-offs like The Brady Bunch Variety Hour or The Brady Brides.
First movie was the whole 'fish out of water' storyline.
Second was a reversal of that with a normal guy having to live with them.
After that it's hard to think of where they could go.
The Brady Presidency movie was trash.
I guess the next step would be some sort of adventure movie.
The Brady Bunch moves to Australia!
or
The Brady Bunch goes Backpacking!
Yeah, the presidency thing would be ridiculous beyond the level 5 ridiculousness of the parody films.
The Australia thing would work, but really, all they had to do was come up with a minor plot and fill the rest of the film with references to the TV show as they did in the first two.
I read somewhere the next one would have been a crossover with Gilligan’s Island since Carol said her first husband was the Professor.
sharecindy, mike and greg or the whole family go on a rafting journey and end up in .. the land of the lost!
shareMarcia starts a cult dedicated to The Monkees.
shareCousin Oliver stays in with the Bradys.
shareMaybe even crossover into horror, Kitty Carryall goes on a murderous rampage, but to be honest I think 2 were great, and the third, made for TV one showed the reason they should have stopped at 2 😀
