New Sci-Fi Movies & TV Shows Set to Release in December 2025

December 2025 is shaping up to be an amazing month for science fiction lovers! Both streaming services and movie theaters are planning big releases, including exciting action movies and intense dramas. We’ll see the end of one popular, long-running series, and the return of the world of Avatar. There’s something for everyone, from superhero stories from around the globe to thought-provoking thrillers.

‘Resurrection’ (2025)

In a world where people have traded their dreams for the chance to live forever, a lone man still experiences vivid illusions. A woman enters his mind, seeking to understand the secrets of their shared past and the reality they inhabit. This science fiction drama, directed by Bi Gan, examines what it truly means to live forever and whether human consciousness can be preserved. It will be released in select theaters on December 12th, followed by a wider release on December 19th.

‘Avatar: Fire and Ash’ (2025)

James Cameron revisits the world of Pandora in the latest installment, where Jake Sully and Neytiri face a new threat: the Ash People, a fierce and hostile Na’vi clan. Unlike the peaceful tribes we’ve seen before, this group offers a darker side of Na’vi culture, forcing the Sully family to rethink everything they know. As they try to forge an alliance with this new clan, they also continue to fight against the ongoing human colonization. The film promises to be even more visually stunning and expansive than previous installments, hitting theaters on December 19th.

‘Stranger Things’ (2016)

The hugely popular series is ending with a final showdown between the people of Hawkins and the terrifying Vecna, along with the creatures from the Upside Down. Netflix will release the first part of the final season on December 25th, and the remaining episodes on December 31st, creating a major New Year’s Eve event for fans. The creators, the Duffer Brothers, have promised a big, emotional ending that will resolve the decade-long supernatural story.

‘Cashero’ (2025)

This new Korean drama features a regular office worker who gains super strength based on how much money he has. There’s a catch, though: using his powers drains his bank account, so he has to be careful not to run out of funds while trying to save the day! Starring Lee Jun-ho, the show is a funny and action-packed take on the superhero genre, and all episodes will be available on Netflix starting December 26th.

‘The Copenhagen Test’ (2025)

Simu Liu plays an intelligence analyst who realizes someone has hacked his brain, giving enemies complete access to his senses and thoughts. He’s forced to work as a double agent, caught between his own agency and the hackers, to find out the truth without getting exposed. This thrilling sci-fi series delves into the frightening possibilities of constant surveillance and mind control. It begins streaming exclusively on Peacock December 27th.
