For many years, England’s Amicus Productions was the scrappy studio living in the shadow of and following the lead of the higher profile Hammer Studio. In fact, so closely did Amicus follow Hammer’s horror lead that much of their output continue to be mistakenly labeled as Hammer Horror. Amicus often used the same actors — including Peter Cushing and venerated horror film icon Christopher Lee — and directors — including Freddie Francis and Roy Ward Baker — and went for a similar feel. There are, however, several differences. For starters, most of Amicus’ horror films were set in the present day, or at least more recently than Hammer Victorian-era gothic tales. Also, having been founded by Americans, Amicus often looked overseas for established genre talent rather than sticking primarily to English stars. Thus, you get a film like Madhouse or Scream and Scream Again, both of which starred American horror icon Vincent Price. And finally, although Amicus is known these days primarily for their horror output — and especially their horror anthology films like Dr. Terror’s House of Horrors, The House that Dripped Blood, Vault of Horrors, and Tales from the Crypt — they also produced a number of science-fiction and sci-fi tinged horror films. Hammer did this as well, at least for a little while and most successfully with their Quatermass films, but once Dracula, the mummy, and Frankenstein became established hits, Hammer pretty much jettisoned sci-fi in favor of straight Gothic horror. Amicus, on the other hand, constantly dabbled in the speculative genre.
So there have been a couple of reviews now, possibly more, where I’ve claimed that the crummy movie in question would have been much improved had the two leading stars been replaced by actor Doug McClure and actress Caroline Munro. I figured, then, it’s high time I reviewed a crummy movie that did cast McClure and Munro in the lead roles, and when one’s talking crummy films featuring either of those stars, it’s hard to find one that’s much crummier than At the Earth’s Core, a low-budget attempt by England’s Amicus Studio to bring to life Edgar Rice Burrough’s Pellucidar series of novels. Pretty much every pulp fiction writer, from Burroughs to Verne, wrote a hollow earth, beneath-the-surface of the planet adventure. Burroughs, in fact, wrote several, and these attempts to do Journey to the Center of the Earth one better comprise the Pellucidar books.
