Plot centers on American astronauts landing on a planet inhabited by one American scientist, sole survival of a past mission, his gorgeous indigenous-birthed daughter, and some kind of phantom wraith. The mystery builds nicely with the gradual investigation of this new world and its past civilization, and the actors, especially the three leads, keep you lightly interested enough through some cerebral-heavy dialog. The dated but still worthy special effects coincide with some excellent battle scenes. And thankfully the twist ending doesn't have an overly-obvious anti-nuke message, a nice surprise since most fifties sci-fi films lean (and sometimes topple) in that direction.
