Phantom Planet

When two astronauts are sent on a mission to find some vanished colleagues, they crash-land on a strange asteroid. Capt. Frank Chapman (Dean Fredericks) -- the lone survivor -- emerges to find that he's now just 6 inches tall. On the run from the Solonites, the tiny aliens that inhabit the asteroid will do anything to get Chapman's aid -- even let him choose between two of their most beautiful females.
