Fan CastingSuperman 3

An asteroid is on a collision course with Earth, and Superman takes it upon himself to stop it. Before it can ever enter Earth's atmosphere, Superman uses all his herculean strength to destroy it. The job is done, but the exertion causes him to pass out, and he is easily picked up by an alien slave ship. The ship brings Superman, along with a group of other aliens, to the mobile satellite known as Warworld, ruled by the tyrannical Mongul, where Superman will have to fight for his freedom in gladiatorial combat. However, Superman's presence proves inspiring beyond the confines of Earth as he allies himself with other prisoners and inhabitants of Warworld, and starts a revolt to overthrow Mongul. Meanwhile, on Earth, Lois Lane has to hope that Superman is alright, as she carries on with the investigation into Intergang that Clark and she started before the asteroid, and she proves to the world, and mostly herself, that she can still be an investigative journalist without Superman’s help.
