Two Lost Worlds (1950) is a science fiction/adventure film, presenting James Arness in his first starring role (his last name is still spelled "Aurness" in the credits) and Laura Elliott. The film was produced independently by Boris Petroff (dba Sterling Productions Inc.) from his original story. The film was scripted by Phyllis Parker (with later, added scenes written by Tom Hubbard and voice-over narrative by Bill Shaw), directed by Norman Dawn, and distributed by Eagle-Lion Classics Inc., with a 1952 reissue by Classic Pictures Inc.


The year is 1830. The American clipper ship, the Queen, is attacked by pirates in the New Hebrides (present day Vanuatu). The ship's mate Kirk Hamilton (Arness) is wounded and heads to Queensland, Australia for medical treatment. While at the hospital, he meets and falls in love with Elaine Jeffries (Rogers), the fiancee of Martin Shannon (Bill Kennedy) a rancher. A romantic rivalry develops and the pirates, who attacked Kirk and his ship kidnap her along with her friend, Nancy Holden (Jane Harlan). Kirk and Shannon pursue the pirates and they soon wind up on a volcanic island, inhabited by dinosaurs.


There are no original dinosaur effects in the film. The dinosaurs appear 58 minutes into the film during the final reel. They were taken from stock footage recycled from the film One Million B.C. (1940).

The film was shot in Red Rock Canyon State Park (California) in Cantil, California.
