The original Happy Death Day, released in 2017, was a significant success for Blumhouse, grossing over $125.5 million worldwide against a modest $4.8 million budget. Its unique blend of horror, comedy, and a Groundhog Day-esque premise quickly garnered a dedicated following. A sequel, Happy Death Day 2U, followed in 2019, earning $64 million globally on a $9 million budget. While still profitable, its lower box office performance led to uncertainty regarding a third film, despite strong interest from both Rothe and Landon.

Producer Jason Blum had previously expressed hesitation, citing the sequel's returns, though he later reassured fans that a third movie wasn't entirely off the table. Now, Rothe's latest update provides the most concrete progress yet.

Speaking to Deadline at the recent Toronto Festival, where she was promoting her new horror film River, Rothe shared exciting news about the long-anticipated sequel. "Chris Landon and I finally finished the entire story [for the third film], it was really great," she stated. "We went to a secret place – well, it was a Pain Quotidien halfway between our houses (laughs) – and stayed there for hours figuring out the secrets of the third film. Now, we’re just waiting for Universal and Blumhouse to give us a little financial boost..."

This announcement effectively puts the ball in the studios' court. With the creative vision for the trilogy's conclusion now fully realized by its lead actress and director, the path is clear for Universal and Blumhouse to move forward. A third film would not only satisfy the franchise's fanbase but also offer a chance to bring Tree Gelbman's unique journey to a definitive close, tying up the sci-fi elements introduced in the second movie.

While fans eagerly await news on Happy Death Day 3, both Rothe and Landon remain busy. Rothe has several upcoming projects, including the thriller Imposters, the slasher River, and the survival film Beware Boiúna. Christopher Landon, known for his genre-bending approach, has also directed recent films like Freaky, We Have a Ghost, and Drop Game, continuing to explore horror with a distinct twist.
