Take a bite!
This is a trailer for a film called "The Apple". Made in 1980, it was set in "the future" of 1994, where apparently wearing mylar, sequins and glitter is very important.
I recently saw this at a theatre where they were having a "Can't Stop The Musicals" festival. Described as a sort-of combo of "Xanadu" and "Superman IV", this apple is so bad, it's good.
