The actor spoke to Insider about his return as Scott McCall, reuniting with costars from the MTV series, and the absence of Dylan O'Brien's Stiles in "Teen Wolf: The Movie."

Tyler Posey may not be a teen or a wolf, but his life has been running parallel to Scott McCall's ever since he first slipped into the character's maroon No. 11 lacrosse jersey over a decade ago.

"Scott and I have always sort of had a similar trajectory ever since the show started, because in the first episode, he got bit by a werewolf, his life changed," Posey told Insider. "I got 'Teen Wolf' and my life changed in a different way, but we were still sort of on the same wavelength."
