Hell of a Summer is a 2023 comedy horror film co-written and directed by Stranger Things star Finn Wolfhard and Billy Bryk. Set at Camp Pineway, it follows a group of counselors, including Fred Hechinger's Jason, who are brutally targeted by a mysterious killer wearing a devil mask. The film premiered at the Toronto International Film Festival on September 10, 2023, before receiving a theatrical release from Neon on April 4, 2025. Its key twist reveals that two of the "victims"—a social media influencer and a fellow counselor—faked their deaths and orchestrated the slaughter to gain internet fame. The movie ultimately received mixed reviews, with critics split on its blend of slasher tropes and quirky comedic tone.
