2012's Prometheus is one of the most controversial sci-fi outings of the 21st century, but it is an essential piece of the Alien franchise today.

Most movie franchises start with a big hit, but that wasn't the case for this somewhat improbable sci-fi action series that spawned from a box office flop.

A new indie sci-fi thriller is finally making its way to audiences after several years in development. Electric Entertainment has released the first trailer for The Bunker , a tense alien invasion story starring Chelsea Edmundson ,

The '90s were something of a golden age for science-fiction movies that were classics of their time but have since become memorable for all the wrong reasons.

Remakes generally fail to live up to the original movie, but these five sci-fi examples managed to both match up to and outshine their inspirations.

From an Alien prequel to a Terminator sequel, from a box office bomb to an Oscar-winning sci-fi, no movie is safe from predictable twists.

Silent dramas like Metropolis and pioneering creature features like Godzilla are among the best sci-fi movies released before 2001: A Space Odyssey.
