"Is this a bad joke?!" utters a character when the plot is explained. In all fairness, I can't see how anyone would elevate this to ANY list, good or bad; mediocre but not Ed Woodian or as as bad as "Mesa of Lost Women." The oddity of the film is that some 1970's people added some footage at the beginning, which doesn't advance the plot but does highlight that the ORIGINAL, in contrast, had higher production values which viewers dismiss. Why they added more is a mystery: to finish the film? to change its politics (women's lib)? Given the fact that it was probably too expensive to replicate the "look" of the original footage, it was probably a money-making scheme. The original was on a par with other low-budget films like "Beatniks," "Teenagers from outer space", etc., with a few recognizable actors. Add to that it's intentionally funny moments (husband-wife banter, a beatnik sister, an improbable marriage at the climax) makes this NOT a topper for movie Baddom. What would have been interesting was if the amateur 1970's filmmakers had disassembled the film, like Steve Martin's "Dead men don't wear plaid" or Woody Allen's dubbed spy movie "What's up tigerlily"(surely the granddaddy of MST3K). As for the misnamed title, 2 other 'head' films also avoid using "head": "Brain that wouldn't die"(though they change the movie title at the end from brain to head) and "Thing that couldn't die." I guess "head" just doesn't sound scary. And the other complaint that 'Mr. H'(aka Hitler) doesn't say anything, well, it's not the Biography Channel; besides, what else would he say?: "Will someone PLEASE scratch my nose?!" For this invasion he's literally just a figurehead/paperweight (one of the characters alludes to this), and his head without a body aptly metaphors the Nazi totalitarian society where noone must feel anything (what would Nazis do on a Saturday night?). As Mr. H's plans backfire again, you'd think he'd learn from history: two wrongs don't make a Reich.
