As of now, there is no official announcement regarding a "Maze Runner 4" movie. The "Maze Runner" film series, based on the books by James Dashner, concluded with "Maze Runner: The Death Cure" in 2018. While there have been discussions about potential spin-offs or new projects related to the franchise, nothing has been confirmed. Fans should keep an eye on news from the studio or the author for any future developments.

Yes, "Maze Runner: The Scorch Trials" is the second movie in the "Maze Runner" film series, following "The Maze Runner," which was released in 2014. "The Scorch Trials," released in 2015, continues the story of Thomas and his fellow Gladers as they navigate a desolate landscape known as the Scorch while facing new challenges and threats from WCKD, the organization behind the maze trials. The film is based on the second book in James Dashner's "Maze Runner" book series.

"Maze Runner: The Scorch Trials" differs from the first film primarily due to its expanded scope and departure from the book's plot. While the first movie focuses on the Gladers' escape from the Maze, the sequel shifts to a broader world where they face the harsh realities of the Scorch, a desolate wasteland. This change introduces new characters, themes of survival, and explores the effects of the Flare virus. Additionally, the film emphasizes action and suspense, diverging from the original novel's storyline, leading to a more intense, fast-paced viewing experience.

As of now, "The Maze Runner 2025" does not exist; there is no official announcement regarding a new film titled "The Maze Runner" set for release in 2025. The last movie in the series, "Maze Runner: The Death Cure," was released in 2018. If you are looking to watch the existing "Maze Runner" films, they are available on various streaming platforms such as Hulu, Amazon Prime Video, or rental services like Google Play and iTunes, depending on your region.
