Fox redressed this set from their lavish big budget musical "Hello Dolly"(1969)into the mutant's post-apocalyptic "Cathedral" in "Beneath the Planet of the Apes" (1970). "Hello Dolly" was a huge box office failure that nearly took down 20th Century Fox, so they REALLY needed to watch their pennies.
