Collider senior writer Ryan Heffernan has published a ranked list, dated 6 July 2026, of the six best science-fiction films released in the first half of 2026. The piece argues that the year has already lived up to the genre's long tradition of cinematic excellence, even as audiences anticipate the forthcoming Dune: Part Three.

The article counts down from number six, covering major box-office releases and lesser-known titles tipped for future cult status. Ranked sixth is War Machine, a Netflix action film starring Alan Ritchson as a soldier facing a robotic entity, praised as an 80s-style throwback. Fifth is Steven Spielberg's Disclosure Day, an alien-contact conspiracy thriller with Emily Blunt and a John Williams score, deemed ambitious if short of Spielberg's best. Fourth is Good Luck, Have Fun, Don't Die, a Sam Rockwell time-travel dark comedy that lost money at the box office but is seen as a likely cult classic. The article's top three entries are not included in the supplied text.
