Two horror powerhouses are merging into one behemoth, as Jason Blum’s Blumhouse and James Wan’s Atomic Monster have completed their long-awaited merger, Blum announced on Tuesday via X (formerly Twitter).

“Our deal is …. Done. @blumhouse and #AtomicMonster have officially joined forces,” the prolific producer wrote in a message including a reel showcasing both companies’ filmographies. “The preeminent homes for horror are now under one roof.”

The merger news comes just days ahead of the release of supernatural horror pic Night Swim, which is produced by both companies and stars Falcon and the Winter Soldier‘s Wyatt Russell alongside The Banshees of Inisherin actress Kerry Condon. The two production houses previously collaborated on last year’s TikTok sensation M3GAN.

Per Deadline, “the companies will continue to operate as separate labels, with each maintaining its own creative autonomy and brand identity. The alliance is expected to increase their combined output, with Atomic Monster to utilize Blumhouse’s existing infrastructure to scale its activities across film, TV and new content areas including games, live experiences and audio. Going forward, Atomic Monster will also benefit from the first-look deal with Universal Pictures that Blumhouse is currently under, having come to the conclusion of its own deal with Warner Bros.”

So essentially, this Blumhouse-Atomic Monster merger just means more horror entertainment all around!
