Production
The film was based on a BBC radio serial written by John Beldon. Location shooting was done along the River Thames and at Falmouth and St Mawes. The railway station at which John Witty - Doctor David Galloway - arrives in Cornwall was St Ives. The branch is still open, and the area still similar today.
