The Goonies and Lord of the Rings star Sean Astin has joined the cast of Cabin Fever: Patient Zero, the upcoming installment in the franchise started by Eli Roth’s 2002 indie horror, Cabin Fever.

The movie is actually one of two new movies on the way, the other titled Cabin Fever: Outbreak. When we first told you about the two movies last November, they were said to be sequels. Now it’s unclear what they are. Some say a reboot or spin-offs, perhaps prequels…who knows. But they are Cabin Fever movies, that much is true.

When Eli Roth‘s directorial debut Cabin Fever first hit theater screens back in September 2003 it had been riding a mighty wave of hype following several successful film festival showings.

Unfortunately that hype and the modest marketing muscle that a pre-Saw Lionsgate (back when they were Lions Gate) could muster couldn’t translate to boffo box office for Roth’s movie. Despite the failure of Cabin Fever to become a new blockbuster horror franchise the film managed to gross $30 million worldwide off a $1.5 million production budget and did even better on home video.
