Considering that Kate and Mike met working on a horror movie, it should come as no surprise that they've continued to collaborate on several other projects, mostly in that same genre. The duo cowrote the 2016 film Hush, in which Kate also starred and Flanagan directed, and Kate also starred in Ouija: Origin of Evil later in 2016, and Gerald's Game in 2017.
The couple's biggest collaboration so far has been on Netflix's The Haunting series, which Mike created. Kate starred as the middle Crain sibling, Theodoura (aka "Theo") in The Haunting of Hill House, then returned for a role as the haunting Viola Willoughby in the anthology's next entry, The Haunting of Bly Manor.
