Clutch Cargo: The Haunted Castle

This animated cliff-hanger serial centers on Clutch Cargo, a writer and pilot who is sent around the world on dangerous assignments! Accompanying him are his young ward Spinner and his pet dachshund, Paddlefoot. The show is infamous for its use of the "Syncro-Vox" technique, which superimposes live-action human lips over limited-motion animation cells.
