"McBain" was The Simpsons' spoof of 1980s action movies, openly parodying the likes of Die Hard, Lethal Weapon, Dirty Harry, James Bond, and anything starring Gov. Arnold. Some years ago, as I'm sure you've heard, some enterprising people realized that all of the bite-sized McBain clips could be assembled into a "full-length movie," and stitched everything together. It's actually quite entertaining; not exactly an intended hidden film, but more of a happy accident. You could probably do the same with all those '80s action movies.
Kids today are probably scratching their heads at that '80s Rambo culture. It was everywhere, in our movies, our video games, even our foreign policy. The old geezers in the Ronald Reagan administration certainly watched too many McBain movies, that's for sure. Ah, well. Time to punch up the Konami code for 30 lives, sit back, and have a few laughs with The Simpsons (insert tired "when they were cool" joke here).
