Rot: Matthew Lillard and Amber Midthunder to star in Mike Flanagan–Produced body horror

Rot, Alexandra Magistro’s feature debut, stars Matthew Lillard, Amber Midthunder, and Cooper Koch. Magistro will direct, with Mike Flanagan executive producing through Red Room Pictures.

From Black List script to Vancouver production

Rot originates from a 2024 Black List screenplay authored by Geo Bradley. Bradley characterizes the project as blending a Repulsion-like mood with Cronenbergian body horror. Principal photography is slated to start in Vancouver in November, with Molly C. Quinn, Matthew M. Welty, and Elan Gale of QWGmire serving as producers in collaboration with Flanagan.

Talent and creative team

The cast is led by Matthew Lillard, alongside Amber Midthunder and Cooper Koch. Alexandra Magistro makes her feature debut as director, with Flanagan producing under his Red Room banner.

Premise and tonal note

The story follows an antisocial man with obsessive compulsions who, after the death of his hoarder mother, takes a trauma-cleaning job to confront his past. The assignment soon begins to infest and unravel his mental state.

Red Room Pictures and next steps

Rot sits within Red Room Pictures’ evolving slate, including Flanagan’s involvement in other projects such as Carrie adaptations and a Stephen King The Mist adaptation. The project marks another collaboration between Magistro and Flanagan as they extend Red Room Pictures’ feature horror slate.
