Director Christopher Landon weighs in on the discussion surrounding a potential Happy Death Day and Freaky crossover, addressing the current likelihood on the project ever going ahead. Landon directed 2017's Happy Death Day, which stars Jessica Rothe as a college student caught in a time loop on her birthday, forced to relive her shocking murder over and over until she unmasks her killer. The director would helm the sequel, Happy Death Day 2 U, before working on 2020's Freaky, which starred Kathryn Newton and Vince Vaughn as a teenage girl and serial killer who are unintentionally subjected to a body swap.
