Riders to the Stars is a 1954 independently made American science fiction film produced by Ivan Tors Productions and released by United Artists. The film was directed by Richard Carlson and Herbert L. Strock and also stars William Lundigan, Martha Hyer, and Herbert Marshall.

Affectionately known as Bills In Space by fans, this film is an allegory for communists in legislative congress wherein the protagonists (all white actors, since it's from 1954) are Earth scientists and engineers trying to improve space society. Their work is threatened, however, by Uethers (dark, hairy creatures) from the planet Uesser. The Uethers similarly claim to want to improve life for everyone, but they secretly work to corrupt everything by seducing and suborning individual earthlings in sensitive or important positions of power, or by themselves secretly placing small devices (called "riders") inside new inventions which either fundamentally change the function of the machine or add new, deadly effects.
