2025 is going out with a bang.

From long-awaited sequels and new fantasy worlds to huge AAA game launches, December 2025 and early 2026 are stacked with releases that deserve a place on your watchlist (and wishlist).

Here’s a fan-curated MGTDb rundown of 7 upcoming movies, TV series and games you should have on your radar.

🎬 MOVIES

1. Avatar: Fire and Ash (Cinema)

James Cameron is back on Pandora for the third chapter in the Avatar saga, reportedly diving deeper into the “Ash People” — a more aggressive, fire-aligned Na’vi clan that will test everything we think we know about this world.

• Release date: Currently scheduled for December 19, 2025 (cinemas)

• Where to watch: Theatrical release first, streaming later (platform TBA)

• Why it’s hot:

  • Expands the lore of Pandora with a darker, more hostile Na’vi culture

  • Expected to push VFX and 3D even further

  • Sets up the back half of Cameron’s long-planned Avatar saga

MGTDb take: If you love epic sci-fi worldbuilding and big-screen spectacle, this is the December event movie.

2. Wake Up Dead Man: A Knives Out Mystery (Netflix)

Detective Benoit Blanc returns for his third outing after Knives Out and Glass Onion. This time he’s wrapped up in another twisted murder mystery with a fresh all-star ensemble cast and Rian Johnson back writing and directing.

• Release date: December 12, 2025

• Where to watch: Netflix worldwide

• Why it’s hot:

  • Daniel Craig back as Blanc = instant watch

  • Knives Out mysteries have become a yearly “event night in”

  • Expect sharp social commentary wrapped in a fun whodunit puzzle

MGTDb take: Perfect for a December movie night with friends, family, or just you and a hot drink trying to solve the case before Blanc does.

3. Five Nights at Freddy’s 2 (Cinema)

Five Nights at Freddy's 2 | Official Trailer 2

Freddy and friends are clocking back in. The sequel to Blumhouse’s hit game adaptation is set to return to the haunted animatronic chaos, with more lore, more scares, and (probably) even more screaming TikToks.

• Release date: December 5, 2025

• Where to watch: Theatrical release

• Why it’s hot:

  • Built-in fanbase from the games and the first movie

  • A prime December horror fix for anyone who hates waiting until Halloween

  • Tons of theory fuel for FNAF lore hunters

MGTDb take: If haunted animatronics and jump scares are your thing, this is your early-December horror treat.

📺 TV SERIES

4. A Knight of the Seven Kingdoms (HBO / Sky / NOW)

A Knight of the Seven Kingdoms | Official Teaser Trailer | HBO Max

Westeros returns — but not the way you’re used to. Based on George R.R. Martin’s beloved Dunk and Egg novellas, A Knight of the Seven Kingdoms follows Ser Duncan the Tall and his mysterious young squire Egg about 100 years before Game of Thrones.

• Release window: Early 2026

• Where to watch: HBO / Max in the US, Sky / NOW in the UK and select regions

• Why it’s hot:

  • A smaller, more intimate story compared to the massive wars of Thrones

  • A fresh entry point into Westeros for new viewers

  • Already renewed for a second season, showing HBO’s confidence

MGTDb take: If you’ve missed political schemes, knights, and dragons (or you bounced off the later Thrones seasons), this could be your perfect way back into Westeros.

5. The Abandons (Netflix)

The Abandons | Official Trailer | Netflix

From Kurt Sutter (Sons of Anarchy), The Abandons is a gritty Western series set in 1850s Oregon, following families pushed to the edge by ruthless power and land grabs. It’s violent, emotional, and packed with frontier tension.

• Release date: December 4, 2025

• Where to watch: Netflix

• Why it’s hot:

  • Mixes family drama with brutal frontier justice

  • Strong cast and a showrunner known for intense, character-driven storytelling

  • Arrives right as people are hunting for a new binge over the holidays

MGTDb take: If you loved Sons of Anarchy, Yellowstone, or morally messy anti-heroes, this should be on your December watchlist.

🎮 VIDEO GAMES

6. MARVEL Cosmic Invasion (PC, Xbox, PlayStation, Switch)

Marvel is dropping a new cosmic-scale adventure that throws heroes into deep-space conflict, with a release across basically every major platform. According to recent release calendars, it lands right at the start of December.

• Release date: December 1, 2025

• Platforms: PC, Xbox Series X|S, PS5, PS4, Nintendo Switch

• Why it’s hot:

  • Marvel + big cosmic threat = huge potential for fan-service and deep cuts

  • Multi-platform launch means almost everyone can jump in

  • December timing makes it a prime “holiday break” game

MGTDb take: If you love Marvel and co-op or story-driven action games, this could be the last big superhero game event of 2025.

7. Assassin’s Creed Shadows (Switch 2 Version)

Assassin's Creed Shadows – Announcement Trailer – Nintendo Switch 2

Assassin’s Creed Shadows already made waves on current-gen platforms earlier in the year, but a special version is set to arrive for Nintendo’s next-generation Switch successor in December. It brings the full feudal-Japan AC experience to handheld players.

• Release date (Switch 2): December 2, 2025

• Platform: Nintendo Switch 2 (next-gen Nintendo system)

• Why it’s hot:

  • Feudal Japan has been one of the most requested AC settings for years

  • Switch 2 version lets you take that fantasy anywhere, handheld

  • Great option for players who skipped on the earlier console/PC release

MGTDb take: For stealth fans and AC veterans, this is a must-play — especially if you’re planning to pick up Nintendo’s next console.
