Skinwalkers is an upcoming werewolf horror/action/thriller film directed by James Isaacs, the director of another horror film, Jason X. The film stars Jason Behr, Elias Koteas, and Rhona Mitra. The film was originally expected to hit theaters on December 1, 2006, but was later pushed to a release on March 30, 2007, and again pushed back to July 27. The film has now been set to be released on August 10, 2007.

Skinwalkers marks Lions Gate Entertainment's first collaboration with Constantin Films, which created other sci fi films, such as Resident Evil, Resident Evil: Apocalypse and Wrong Turn. The special effects will be handled by effects house "Mr. X", which has done films such as the Dawn of the Dead (2004). This film also marks Lions Gate Entertainment's first collaboration with Stan Winston who created the effects for the Terminator films, the Jurassic Park franchise, Interview with a Vampire and the film War of the Worlds.

Director James Isaac has said, "Skinwalkers is unique because it has a great story, compelling characters, amazing special effects, action and stunning visuals. All of these elements come together in a way that is very organic to the story. I am very excited about the team of filmmakers involved in this project."

Two packs of werewolves, divided by principles, are signaled by the moon of the coming of an ancient prophecy. A young man named Timothy (Knight) approaches his 13th birthday, unaware this marks the time of his transformation. Timothy has been raised by his mother Rachel (Mitra), his grandmother (Gordon), his Uncle Jonas (Koteas), his cousin Katherine (Carter) and Katherine's boyfriend, Adam (Roberts).

Rachel and Timothy have been unaware that the rest of the family are "good" werewolves that have guarded Timothy and his secret since birth. They know that Timothy is a half blood, and will control the destiny of the family. But they also know that Timothy's power will put him in danger, for there are other werewolves that revel and embrace their blood-lust that are prepared to kill to preserve their way of life. These werewolves, led by Varek (Behr), Zo (Coates) and Sonya (Malthe), are hell bent on finding Timothy; their kin.

Previously, the film has been rated R for "violent content throughout and language". Now, the film is rated PG-13 for "intense sequences of violence and action, sexual material, and language".

Varek (Jason Behr) — Leader of the evil werewolves.

Jonas (Elias Koteas) — The Alpha of the pack sworn to protect Timothy, and father of Katherine. Like the others, he keeps himself restrained on the full moon and wants their curse to finally end.

Rachel Talbot (Rhona Mitra) — A widow, hard-pressed to cope with her frail son Timothy's frequent illnesses. She doesn't know her family and community is made up of werewolves.

Zo (Kim Coates) — The Beta, or second in command in Varek's pack.

Sonja (Natassia Malthe) — The Alpha female in Varek's pack, and his mate. Was once human, with a seemingly miserable life until sired by Varek. Is very neurotic, and completely loyal to Varek, and obsessed with him.

Timothy (Matthew Knight) — A half-blood, the offspring of a male werewolf and Rachel. He holds the power to control the destiny of his family, and the entire werewolf race along with him. He is protected by Jonas and is Varek's target.

Katherine (Sarah Carter) — Jonas's daughter and a werewolf as well. She has a boyfriend named Adam.

Grenier (Rogue Johnston) — One of Varek's henchmen. He is mute and has a heavily scarred face.
