Hammerstone Studios has cast Cooper Tomlinson, Jessica Rothe, and Mika Abdalla in Seeker, a horror film directed by Adam Rehmeier from an original screenplay by Michael Learner. The story follows Grant, a ride-share driver haunted by the disappearance of his fiancée Caroline five years earlier.
Why it matters

The project carries a January 2027 production start in Washington State and a five-year backstory driving its central character. Release timing, budget, and distribution plans were not disclosed in the announcement.

Industry Dynamics
Seeker's multi-studio backing, with HyperObject Industries, Arkhum Productions, and north.five.six joining Hammerstone, reflects the co-financing model used for mid-budget genre films. Its compact premise of a single ride and a single obsession follows the lean, character-driven structure that has sustained independent horror and thriller production.
Viewers will have to wait for release details, as no distribution platform or theatrical date has been announced yet. Production in Washington State is set to begin in January 2027, so the film is still in its early development stage.
The takeaway
A premise built around one ride and one unanswered question can carry a whole film, and Seeker's casting shows how that kind of lean story still attracts a cast and a multi-company team.
