The German crew members disobey Tyler’s orders and head for a German port in the South Pacific. However, the crew find themselves lost and surface in a land where modern time appears to have been forgotten as pre-historic creatures and lesser evolved humans co-exist. Captain Von Schoenvorts and Lisa engage in their mutual love of biological research while Tyler tries to find a way out of this Lost World. The crew encounter attacks from sea, land and air, together with tribal attacks.
The wires and moveable parts of the models in Connor’s film are clearly visible throughout but you can forgive that when you consider the scope and ambition on show in an era long before CGI.

An interesting interview with Kevin Connor shows his fondness for his classic sci-fi. Also included is an interview with Susan Penhaligon - she faced the decision to take on a monster movie or a role for the Royal Shakespeare Company.
