Kevin Bacon is set to star in “Summoner,” a new horror film for Amazon MGM, with writer-director Jeremy Slater making his directorial debut. The project is described as a genre thriller that follows Jefferson Haddock, a character called to an isolated witness protection property. Once there, Haddock must deal with a terrifying demon, a situation that escalates into a larger supernatural threat. Both outlets report that Slater, known for prior work in genre screenwriting, is taking on directing for the feature. Amazon MGM is developing “Summoner” as a theatrical release. While details on production dates and supporting cast are not provided in the available excerpts, the reporting agrees on the key elements: Bacon’s casting, the studio behind the film, the title “Summoner,” and Slater’s dual role as writer-director for his first time directing a feature.
