Carrie-Anne Moss Joins Halsey’s Horror Movie Replacer, With a Wachowski Already on Board

Carrie-Anne Moss has joined the cast of Replacer, the horror film Halsey co-wrote and stars in for director Avan Jogia. Deadline reported the casting on Monday, and it comes with a second piece of news: the film has already finished shooting in Montreal.

That makes Moss a late reveal rather than a new hire. Replacer was scheduled to start filming on September 16, so she is being announced after the fact, as the film heads to the American Film Market to find buyers.

What Replacer is about

Halsey plays Proxy, a troubled DJ stranded in Montreal who falls in with an artist and his friends, the crew behind an underground radio station. Their broadcast gets warped by a signal coming from deep beneath the city’s subway system, and Proxy has to get out before the sound turns her and everyone around her into, per the official synopsis, “something raw, primal, and unrecognizable.”

The film has been billed as a “psycho-sexual horror” since it was first announced at the Cannes market in May. Jogia, who wrote the script with Halsey, described it then as “a bright and electric club horror mashed together with a vulnerable romantic story about belonging and community.” Deadline has called it Halsey’s first lead role in a film, after supporting parts in MaXXXine and Americana.

The Matrix connection

Moss isn’t the first Matrix name attached. Lilly Wachowski, who created that franchise with her sister Lana, came aboard as an executive producer when the project launched in May. She called the script “a surreal hyper-dive into a twitchy, conspiratorial genre mashing snarl of horror/thriller/comedy, set against the grit and grime of a rarely glimpsed Montreal subculture.”

So Replacer now puts Trinity in a movie backed by one of the people who wrote her. Moss has played the character across four Matrix films, most recently 2021’s The Matrix Resurrections. She is no stranger to horror either, with Silent Hill: Revelation and The Bye Bye Man on her résumé, and Marvel viewers know her as attorney Jeri Hogarth from Jessica Jones.

Who else is in it

Karl Glusman (The Neon Demon) and Juliette Gariépy (Red Rooms) joined in September. The cast also includes Antoine Olivier Pilon (Mommy), Landon Liboiron (Hemlock Grove), Nhi Do, Gabriel Carter, Audrey Roger, Estelle Fournier, Joephillip Lafortune and Martin Debreuil. Electronic producer Boys Noize (Alex Ridha) is scoring the film, which fits a story about a DJ and a cursed broadcast.

Replacer does not have a distributor or a release date yet. When it launched at Cannes, CAA Media Finance and UTA Independent Film Group were handling North American rights, with Film Mode Entertainment selling it internationally.
