A great crossover idea that never happened...
I was thinking about this idea last time i saw the Brady Bunch Movie, i think it would've been really funny to see a Brady Bunch/Addams Family movie crossover since they both used similar humor styles (socially inept moments with real world people, awkward family, based off old tv shows.)
Not to mention the two families are completely opposite, and the culture clash would've been great. i think it would've made for some funny moments since i love both movies. I wish there were more of each series i guess
