EXCLUSIVE: After studying the minds of serial killers in David Fincher’s Mindhunter, Holt McCallany will further mine the territory as the lead in Hyde, a noir-tinged thriller from filmmakers Graham and Parker Phillips (Rumble Through the Dark) that has entered production in Bucharest, Romania.

Hyde has McCallany playing Detective Grimes, a haunted investigator descending into the decaying underbelly of a crumbling metropolis while hunting a brutal serial killer.

Directing from their own script, Graham and Parker Phillips are also producing through Phillips Pictures alongside Jason Tamasco and Zak Kristofek for Traction. Cassian Elwes will serve as executive producer alongside Keith Danko, Bailey Rotsky, and IDEA Film’s Ionut Ionescu and Andreea Apetre, whose company is serving as a Romanian production partner, providing infrastructure and operational support from its Bucharest offices.

The Phillips brothers told us, “We’re thrilled to be working with such intelligent and collaborative actors. Everyone arrived with bold ideas, strong instincts, and a real willingness to explore and take risks, all against the backdrop of Bucharest, whose architecture and atmosphere feel tailor-made for this twisted tale.”

Traction’s Tamasco and Kristofek added, “it’s a privilege to have Holt join and lead this cast alongside Nathalie, Bruce, and David. We could not be more excited about the team that has come together and the film we’re creating here in Romania. We cannot wait for audiences to experience Hyde.”

McCallany is coming off of turns in The Waterfront, Mission: Impossible – The Final Reckoning opposite Tom Cruise, The Amateur with Rami Malek and The Iron Claw. Among his upcoming projects is The Adventures of Cliff Booth, from his Mindhunter collaborator Fincher, which is set to release in Imax on Nov. 25 before making its way to Netflix on Dec. 23. He is repped by Buchwald, Atlas and Goodman, Genow, Schenkman.

On television, he is known for starring in The Resident, The Fall of the House of Usher, American Crime Story and Dark Winds.
