Prior to 1968, science-fiction was seldom taken too seriously and a risky financial endeavor, meaning studios were rarely willing to do more than pump-out low-budget drive-in fodder aimed at undiscriminating kids. But as the genre increased in popularity - especially during the 1950s - so did the creativity and budgets, resulting in some undisputed classics and underappreciated gems.
These are our picks for the 10 best science-fiction films made before 1968. For the sake of argument, we’ve excluded hybrid films - such as Frankenstein, Them! and The Thing - which placed a greater emphasis on horror. And while giant monsters are awesome and there’s been some great ones, we feel the likes of King Kong and The Lost World fall more within the action-adventure genre.
