“A must-watch for any sci-fi completist. The first full-length feature to tackle the Hollow Earth genre remains deadly serious and never relents in its bleak cynicism.” - Scifist
In this Cold War variation on JOURNEY TO THE CENTER OF THE EARTH, scripted by Oscar nominee Millard Kaufman (BAD DAY AT BLACK ROCK) – and possibly by blacklisted Oscar-winner Dalton Trumbo – Fifties sci-fi took a startling turn into a grim abyss. As the world teeters on the brink of nuclear annihilation, a renegade scientist (veteran character actor Victor Kilian, uncredited due to his own blacklisting) assembles a team of experts to drill deep into the earth’s core in search of a new ecosystem where humanity can survive.
