No, not the 1953 (A vintage year I say) Rock Hudson and Yvonne De Carlo movie, but those monsters that first appeared in Dr Who way back in February 1972.

These are the first episodes that I remember watching of Dr Who, although I have since watched all of the earlier series.

Several ships have gone missing off the British coast, and the Doctor suspects an unnatural cause. Investigating an old sea fort at the epicentre of the disappearances, he comes face-to-face with the aquatic cousins of the Silurians, nicknamed Sea Devils. Like the Silurians, they have lain dormant for aeons in suspended animation, but have recently been awakened. But even as the Doctor starts to formulate a plan to achieve peace with the Sea Devil colony, the Master is plotting too. Having duped the governor of the prison where he is incarcerated, he now plans to help the Sea Devils destroy humanity.

Royal Navy archive footage, ships and sailors were used in the filming of these episodes. The models will provide some interesting ship board scenarios.
