The poster to the tragically-unmade Hammer film Zeppelin v Pterodactyls.
(Ganked from Airminded, which will be of minority interest to most of you, but of great interest to a few).
Airminded provides a link to this plot summary:
"The story was along the lines of THE LAND THAT TIME FORGOT, with a German Zeppelin being blown off-course during a bombing raid on London and winding up at a “lost continent”-type place."
Zeppelin v Pterodactyls would have been the Hammer version of David Allen's Raiders of the Stone Rings, later called The Primevals.
Ah, what might have been.
Of course, what we need now is the sfx team behind Sky Captain and the World of Tomorrow to hire a good team of writers and make Zeppelin v Pterodactyls.
(Edit: Forgot to add: last night I got to see a theremin played live--the theme to High Anxiety and the "Creation of the Monster" sequence from Bride of Frankenstein).
