Alex Wolff has done his fair share of emotionally-daunting films, coming off movies like "Hereditary" and "Pig." But working with director M. Night Shyamalan on his laterst film "Old," the actor says he learned something new from the man he calls his "hero." "I feel like a big thing I learned from him is to not bring your process into a movie necessarily, and instead to adapt to his process," Wolff told TheWrap.
