James Gunn, a major figure among Hollywood filmmakers, has a notable filmography stretching from superhero franchises to lesser-known titles. As of December, Gunn’s only foray into directing a pure horror movie is now available at no cost on Tubi, offering fans of the genre a chance to revisit his early directorial work while expanding the reach of James Gunn horror movie streaming.
James Gunn’s First Horror Film Arrives for Free Online
Before making waves with Marvel and DC, James Gunn established his presence behind the camera with the horror comedy “Slither” in 2006. This film, which he both wrote and directed shortly after scripting Zack Snyder’s “Dawn of the Dead” remake as well as “Scooby-Doo 2: Monsters Unleashed,” marked Gunn’s directorial debut. “Slither” tells the story of an alien organism landing in a small South Carolina town, intent on consuming all life on Earth.
The movie began streaming for free on Tubi on December 1st, giving horror fans and newcomers the opportunity to experience Gunn’s first feature as a director. The cast features recognizable names such as Nathan Fillion, Elizabeth Banks, Tania Saulnier, Gregg Henry, and Michael Rooker, all of whom bring humor and intensity to the chaotic invasion narrative. The film’s setting enhances the sense of isolation typical of small-town horror, with the threat spreading quickly among unsuspecting townsfolk.

Why “Slither” Remains a Standout in Gunn’s Career
While James Gunn later became synonymous with blockbuster franchises like “Guardians of the Galaxy” and “The Suicide Squad,” many critics and viewers highlight “Slither” as one of his best achievements, especially for horror fans. The movie draws inspiration from 1980s horror classics like “Night of the Creeps” and John Carpenter’s “The Thing,” translating that fondness for genre filmmaking into an experience rich with both discomfort and laughs.
“Slither” is particularly known for its use of outrageous practical effects, bringing to life grotesque body horror moments such as alien slugs infecting humans and graphic transformations. The balance of sharp, witty dialogue with over-the-top gore demonstrates early signs of Gunn’s future style—irreverent yet heartfelt, comedic but grounded in genuine affection for his genres of choice.
Despite the creative strength of “Slither,” the film struggled at the box office, earning just $12 million on a $15 million budget. However, its critical reception told a different story: the movie attained a Certified Fresh rating of 87% from critics on Rotten Tomatoes, placing it behind only Gunn’s widely celebrated superhero projects like “Guardians of the Galaxy,” “The Suicide Squad,” and “Avengers: Endgame.” For audiences, the approval score rests at a solid 63%, making it one of Gunn’s top fifteen in terms of viewer response and further helping establish it as an enduring cult favorite.
“Slither’s” Influence and Cult Following
In the years since its initial release, “Slither” has achieved an important place both in James Gunn’s career and among genre devotees. The film regularly appears on best-of lists dedicated to horror films from the 2000s and is repeatedly recommended as a must-see for anyone seeking to understand the evolution of modern monster movies. The dedication of its community of fans ensures that the movie continues to find new audiences, particularly now that it is accessible via free streaming.
The cast of “Slither”—including Nathan Fillion, Elizabeth Banks, Tania Saulnier, Gregg Henry, and Michael Rooker—helped develop memorable characters whose chemistry anchors the chaos. This aspect resonates with viewers, as seen in the loyal cult following the film has fostered over almost two decades. Such a response from horror fans highlights the enduring appeal of Gunn’s early style and his willingness to blend humor, heart, and extreme spectacle.

Looking Ahead: The Lasting Legacy of Gunn’s Horror Work
The addition of “Slither” to free streaming platforms marks a meaningful moment for fans of James Gunn, horror enthusiasts, and general movie lovers.
