Star Wars: Episode IV – A New Hope (1977)
George Lucas’s audacious space opera exploded onto screens, grossing over $775 million and birthing a franchise that reshaped Hollywood. Set in a galaxy far, far away, it follows young Luke Skywalker’s rebellion against the oppressive Empire, blending Joseph Campbell’s hero’s journey with Flash Gordon serials.

Culturally, it democratised sci-fi, making it accessible yet mythic.

Alien (1979)
Ridley Scott’s claustrophobic masterpiece fused horror with sci-fi, introducing the xenomorph as a nightmare predator. Ellen Ripley’s crew aboard the Nostromo investigates a distress signal, unleashing terror in H.R. Giger’s biomechanical designs. Scott’s direction—stealthy pacing, practical gore by Carlo Rambaldi—builds dread masterfully.
Sigourney Weaver’s Ripley shattered gender norms, becoming sci-fi’s ultimate survivor. The film’s feminist undertones and corporate critique resonated amid 1970s labour unrest.

-
Solaris (1972)

Invasion of the Body Snatchers (1978)
