Why this series still plays

Voyage to the Bottom of the Sea is Irwin Allen spectacle in a flying-sub hull: Richard Basehart's Admiral Nelson, David Hedison's Captain Crane, and the Seaview meeting monsters, spies, and weekly disaster. It spun from Allen's 1961 film into four seasons of underwater set pieces. Cold War nerves as creature feature — straight faces, big models.
