Jason Blum's Blumhouse and James Wan's Atomic Monster merger deal closes

Jason Blum's Blumhouse and James Wan's Atomic Monster have merged.

Blum confirmed the news in a post on X, formerly Twitter, writing: “Our deal is …. Done. @blumhouse and #AtomicMonster have officially joined forces. The preeminent homes for horror are now under one roof.”

A video showcasing the horror studios' most famous works accompanied the post.

Under the deal, Blumhouse and Atomic Monster will work as separate labels and retain creative independence and brand identity. There is a three-way ownership structure in place, split by Blum, who is the majority owner, Wan, and NBCUniversal's parent company Comcast.

The merger will offer Atomic Monster access to Blumhouse’s existing infrastructure and its first-look deal with Universal Pictures (a deal Blumhouse made with Warner Bros previously). It is expected to increase the output of both studios. 

The companies revealed plans to merge in late 2022. 

The studios have previously collaborated on films including the horror franchise Insidious, M3GAN, and the upcoming film Night Swim.
