While technically a series, the return of Fallout for its second season is arguably the biggest streaming event of the entire week, having premiered on Tuesday, December 16, 2025.

3. Relay (Netflix)

For those craving a taut, intelligent thriller, Relay is the overlooked gem on Netflix this weekend that demands your attention. This 2025 thriller, directed by David Mackenzie (known for the critically acclaimed Hell or High Water), features a stellar cast led by Oscar-winner Riz Ahmed and Lily James.

The film centers on a character named Tom (or Ash), a mysterious New York City "fixer" who specializes in arranging backroom payoffs and complex deals for shady corporations and whistleblowers.

The performances by Riz Ahmed and Lily James are already generating serious buzz, making this a must-see for thriller enthusiasts.

Highly Anticipated Cinematic Releases to Watch For (Theatrical & Future Streaming)

While the focus of this list is on immediate streaming options, two cinematic behemoths are hitting theaters this weekend, December 19, 2025, that will undoubtedly be dominating streaming platforms very soon. Keeping these on your radar is essential for any serious movie buff, as they represent the future of your home viewing experience.

4. The Housemaid (Theatrical Release: December 19, 2025)

The psychological thriller The Housemaid is the biggest new movie hitting the box office this weekend, with a theatrical release date of December 19, 2025. Directed by Paul Feig, this film takes a sharp turn from his usual comedy work, promising a dark, intense mystery.

The star power alone makes it a must-watch: it features Sydney Sweeney and Amanda Seyfried in leading roles, supported by Brandon Sklenar, Michele Morrone, and Elizabeth Perkins. While its streaming home has not been officially confirmed, major theatrical releases like this often land on platforms like Max or Prime Video within weeks, making it the perfect movie to keep an eye on for an imminent home release.

If you venture out to the cinema this weekend, The Housemaid offers a compelling, high-tension narrative that is already being praised for its shocking twists and strong performances, particularly from its two female leads.

5. Avatar: Fire and Ash (Theatrical Release: December 19, 2025)

The third installment in James Cameron's epic saga, Avatar: Fire and Ash, is a monumental cinematic event. Picking up immediately after the emotional and action-packed events of The Way of Water, the film continues the story of Jake Sully (Sam Worthington) and Neytiri (Zoe Saldaña) as they protect the Na'vi people and their home, Pandora.

The plot intensifies as the RDA-led humans, facing a rapidly dying Earth, are now determined to make Pandora their new, permanent home, leading to even greater conflict with the planet’s natives and wildlife. Cameron, who directs and co-writes, expands the mythology, focusing on the new dynamics within the Sully family.

While this is a theatrical-only experience for now, its eventual streaming release will be one of the most significant events of the next year. Watching the first two films, Avatar and Avatar: The Way of Water, this weekend is an excellent way to prepare for the visual spectacle of Fire and Ash.
