‘Mercy’ (2026)

Starring Chris Pratt and Rebecca Ferguson, this sci-fi thriller arrives on streaming platforms on February 17, 2026, following its theatrical run. The story is set in a near-future society where capital punishment has been automated through advanced artificial intelligence. Pratt plays a detective accused of a violent crime who must prove his innocence to an AI judge he once helped implement. With only a short window to clear his name, the film explores the dangers of relying on technology for moral justice.

‘Armorsaurs’ (2025)

Disney+ adds this action-packed series to its catalog on February 18, 2026, launching with its first season. A remake of the South Korean hit ‘Armored Saurus’, the show features a team of pilots who bond with dinosaurs outfitted in high-tech mechanical armor. These “Armorsaurs” serve as humanity’s defense against an extraterrestrial threat known as the Chromedrones. Blending live-action drama with CGI battles, the series targets fans of mecha and creature features alike.

‘Wild Boys: Strangers in Town’ (2026)

Premiering on Paramount+ on February 18, 2026, this two-part documentary series unravels a bizarre true story that captivated a small community. The plot follows the arrival of two young brothers who emerged from the British Columbia wilderness claiming to have been raised entirely off the grid. As the town rallies to support them, inconsistencies in their story begin to surface, leading to a revelation about their true identities. While grounded in reality rather than science fiction, the series explores the psychological depths of deception and belief.

‘Redux Redux’ (2026)

Hitting theaters on February 20, 2026, this sci-fi thriller stars Michaela McManus as a grieving mother trapped in a cycle of multiverse violence. Driven by the loss of her daughter, she travels between parallel realities to hunt down and kill the murderer, played by Jeremy Holm, over and over again. Her mission shifts when she encounters a potential survivor, played by Stella Marcus, in one of the alternate timelines. Directed by Kevin and Matthew McManus, the film uses its 1 hour and 47-minute runtime to deconstruct the tropes of revenge narratives through a mind-bending lens.
