Tales of Suspense #25

A movie producer's next film is a sci-fi picture featuring a giant robotic monster. Bad press convinces him to abandon the project but just as he's about to disassemble the robot, an alien invasion fleet lands. He sends the robot lumbering towards them and they ineffectively fire their nerve weapons at it. Next, they try gas, which of course has no effect on the machine either. Panicked, they flee to their saucers resolving never to return. People express their sympathy to the movie producer that all that money was spent with nothing to show for it, but he knows better.
