Unknown Island

Unknown Island is a 1948 adventure film directed by Jack Bernhard and shot in Cinecolor. The film features monsters such as dinosaurs and a giant sloth and stars Virginia Grey, Phillip Reed, Richard Denning and Barton MacLane. Ray Corrigan also appears in this film, playing a Giant sloth. It also has the giant sloth fight and kill a Ceratosaurus identified as a Tyrannosaurus rex in the movie. A deleted extended scene shows a "Brontosaurus" watch as the dinosaur and sloth fight in a lake nearby; it can be found on the BBC Motion Gallery but the footage is in black and white due to the lack of colour film during the period of austerity immediately following the Second World War.
