Tyler Posey bluntly responds to the constant questions about Dylan O'Brien's absence from Teen Wolf: The Movie. Although several actors from the original Teen Wolf series reprised their roles for the Paramount+ follow-up film, including Posey as the lead character Scott McCall, O'Brien confirmed early on that he wouldn't return as Stiles Stilinski because he felt happy with where he left his character when the show ended. This update fueled a lot of discussions, considering how O'Brien's standout portrayal was central to the success of the MTV supernatural drama and how vital the friendship between Stiles and Scott had been to the core themes of family and friendship that fueled the story.
