In a shocking move, Scott Foley has joined the ever-growing cast of Scream 7. As you know, Foley played Roman Bridger in Scream 3, a villain who is very much deceased. The latest batch of Scream movies are no stranger to utilizing visions and hallucinations to bring back former cast members; just look at Skeet Ulrich in Scream (2022). So it's safe to assume Foley's role will most likely be some sort of flashback, vision, or "archival" footage.
Scott Foley (Scream 3, The Girls on the Bus) has joined the cast of Scream 7 from Spyglass and Paramount Pictures.
Details regarding his character and the film’s plot are currently under wraps. However, Foley is already part of the Scream universe having portrayed antagonist Roman Bridger, the film director and half-brother of Sidney Prescott (Neve Campbell) who was revealed to be the Ghostface Killer of Scream 3.
