Jaden Thompson In Season 2 of “Euphoria,” Sydney Sweeney‘s Cassie famously proclaims that she has “never, ever been happier.” It seems the same cannot be said for her new character Cecilia in the upcoming psychological horror film “Immaculate,” which is set to release in theaters March 22. Directed by Michael Mohan, Sweeney stars as a devoutly religious woman who moves into a haunted Italian convent in the countryside, which seems picturesque on the outside. The newly released trailer from Neon reveals that Cecilia will undoubtedly experience some “suffering” while dealing with a mysterious pregnancy.
