Creation

A submarine discovers a lost island where dinosaurs still roam.

O'Brien designed sets and dinosaur figures which were built by Marcel Delgado for this short-lived project. David O. Selznick scrapped this project when he became head of production at RKO in 1932; however, work already completed on it convinced Selznick's assistant Merian C. Cooper that this technique of filmmaking was feasible. Only a fragment exists, but this work eventually bore fruit as the famous King Kong (1933).
