Lost Continent is a 1951 American black-and-white science fiction film from Lippert Pictures, produced by Jack Leewood, Robert L. Lippert and Sigmund Neufield, directed by Sam Newfield (brother of producer Sigmund Neufeld), and starring Cesar Romero, Hillary Brooke, Chick Chandler, Sid Melton, Hugh Beaumont, and John Hoyt.

An expedition is sent to the South Pacific to search for a missing atomic-powered rocket in order to retrieve the vital scientific data recorded aboard. On an uncharted island, they discover more than their rocket, now crashed atop a mysterious plateau: they find a lost jungle world populated by prehistoric dinosaurs.


Maj. Joe Nolan (Caesar Romero) is the head of an expedition to the South Pacific to retrieve an atomic-powered rocket that vanished without a trace. Their aircraft mysteriously crash-lands on a remote, unknown tropical island in the area where the rocket was lost on radar. They find only two occupants left of the island, a native woman (Acquanetta) and her young son. The woman indicates something fell from the sky atop a forbidding, cloud-shrouded plateau that dominates a part of the island; the rocket's arrival caused the rest of the native population to abandon the island.

Despite numerous obstacles (one of their number is accidentally killed on the ascent) and long, long stretches of tedious rock climbing, the expedition finally reaches the top of the escarpment. Emerging from the toxic, poisonous gas cloud cover, they discover a lush, prehistoric jungle inhabited by various dinosaurs and a large field of uranium, which has sabotaged their electronic tracking equipment. A second member of the expedition is killed during their search of the plateau, gored to death by an angry Triceratops; more danger follows before the rocket's crash site is finally discovered.

Only four members of the expedition manage to return to the island's flatland with the rocket's critical component. This proves to be just in time to escape the island using a native outrigger canoe. The survivors watch from a distance as the island is first rocked by violent Earthquakes and then the catastrophic eruption of the island's formerly dormant volcano, which finally destroys everything: prehistoric jungle, dinosaurs, and all.


This low-budget independent film was shot in just 11 days. All black-and-white footage set atop the prehistoric escarpment was tinted a mint-green color on all theatrical release prints to produce an eerie, other-worldly effect.

The general plot of the film strongly resembles that of Sir Arthur Conan Doyle's novel, The Lost World.


The film was featured in a season 2 episode of Mystery Science Theater 3000 (Dr. Forrester and TV's Frank taunted Joel Robinson before the film began with the words "Rock Climbing." In a host segment Michael J. Nelson portrayed actor Hugh Beaumont as a member of the Four Horsemen of the Apocalypse).

The MST3K episode of Lost Continent was released by Shout! Factory as part of their Volume XVIII series DVD boxed set.
