This Irwin Allen production based on the Sir Arthur Conan Doyle's novel, The Lost World,
dealing with a group of adventurers who come upon a land populated by prehistoric dinosaurs!
And with a great cast including Michael Rennie leading the expedition, Lovely Jill St. John
in one of her very first roles, and David Hedison, memorable as the Fly and as Captain Crane
on Voyage to the Bottom of the sea (for Irwin Allen, when he moved from movie mogul to TV
producer and mogul!). Claude Rains, and Fernando Lamas costar.
