Clunky special effects aside,
THE LAND THAT TIME FORGOT is a decent adaptation of the Edgar Rice Burroughs adventure classic about the discovery of a prehistoric world by a U-boat crew during World War I. This was the first of a series of Burroughs adaptations produced by American International Pictures starring Doug McClure. Followed by
AT THE EARTH'S CORE (1976).
