Was to be created by Hammer Films
Poster was commissioned to get investors. Failed to make funds so was dropped.
Plot synopsis:
Briefly, ZEP began with the late David Allen, Dennis Muren and Jim Danforth. 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. Hammer was interested in the property during the production of WHEN DINOSAURS RULED THE EARTH but developed misgivings about stop-motion animation, plus they couldn’t raise the financial backing, so it was dropped. Allen, in the magazine’s words, “was to continue the property until it evolved into THE PRIMEVALS”.
Unfortunately for us, the poster is awesome and it is a shame this never got off the ground. But that means the Zeppelin vs Pterodactyl market is open for any takers. We’ve had Coolio vs. Pterodactyls, and SciFi Channel also gave us US troops vs. Japanese pterodactyls in WW2 with Warbirds.
