The surreal anti-masterpiece Monster a Go-Go! is an incoherent concoction brewed solely to fill space on a double bill. Bill Rebane's unfinished film Terror at Halfday was purchased by Herschell Gordon Lewis for exhibition with his own Moonshine Mountain, as control over both pieces of a double feature was economically advantageous. The discarded footage was pieced haphazardly together by Lewis (who opted for the pseudonym of "Sheldon Seymour") and explained with officious, and sometimes sarcastic narration. It's hard not to sneer; the prop space capsule couldn't hold a normal sized man (let alone a ten-foot-tall monster), a few irrelevant scenes feel like they've been dropped in from other films, and there's a sudden non-ending where everything stops and the narrator simply explains that everything turned out all right. With a hip frat rock soundtrack and self-deprecating advertisements ("You've never seen a picture like this -- thank goodness!"), Monster a Go-Go! was clearly a film that never intended to stand on its own, and as such feels like a good natured shrug of "ahhh, so what" throughout. Ridiculous pseudo-scientific babble, oatmeal-and-eggwhite makeup for the monster, and a baffling lack of linear logic make it delirious viewing today, and recommended for everyone.
