Lost Continent is a 1951 American black-and-white science fiction film drama from Lippert Pictures, produced by Jack Leewood, Robert L. Lippert, and Sigmund Neufeld, directed by Sam Newfield (Sigmund Neufeld's brother), that stars Cesar Romero, Hillary Brooke, Whit Bissell,[1] Sid Melton, Hugh Beaumont and John Hoyt.

[2] 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.

Their transport aircraft mysteriously crash-lands on a remote, unknown tropical island in the area where the rocket was lost on radar.

They discover a lush, prehistoric jungle inhabited by various dinosaurs and a large field of uranium, which is what disabled their electronic tracking equipment.

Nolan is convinced that Rostov, the scientist who helped make the rocket, is up to no good because he also appeared to be able to save Stanley Briggs on their ascent but failed to do so.

The group soon discover that the rocket is surrounded by a Brontosaurus and a pair of Triceratops, but Nolan devises a strategy using their weapons that scare off the dinosaurs.

The survivors are finally able to watch from a safe distance as the island is first rocked by more violent earthquakes, followed by a catastrophic eruption of the formerly dormant volcano, which ultimately destroys everything.

[3][4] 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.

[2] Special effects for the film were credited to Augie Lohman, but recent research, as per an article in Filmfax #105 (March 2005), posits that the stop-motion for the pterodactyl, brontosaurus, and triceratops, were contracted by Lippert from Edward Nassour, and were likely the actual uncredited work of Jay Baylor and sculptor Henry Lion, who worked for Nassour during that time.

[6] Lost Continent 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.")
