As we reported earlier in the week, Michael Rooker (Henry: Portrait of a Serial Killer, “The Walking Dead”) will be starring alongside Dylan O’Brien in Paramount Players’ Monster Problems, a new monster movie being produced by Shawn Levy’s 21 Laps (“Stranger Things”). Deadline adds today that Ariana Greenblatt (Avengers: Infinity War) will also star.

The young actress will play a character named Minnow.

Michael Matthews (Five Fingers for Marseilles) is directing the film.

Rooker plays Clyde, an expert hunter who teaches Joel Dawson (O’Brien) how to survive the Monster Apocalypse.

Brian Duffield & Matthew Robinson wrote the script, described as “a coming of age story about a young man living in a post-apocalyptic world overrun by monsters.”

The film is being eyed as a potential franchise.
