By Episode 3, we'd abandoned the core family of the first two films to follow ghosthunters Elise (Lin Shaye), Tucker (Angus Sampson) and Specs (Leigh Whannell, who also writes the series).
Not only did Wan direct, but he also co-wrote the film along with his close friend and co-conspirator Leigh Whannell, who also happens to star in the film as «Specs», a ghosthunter of sorts.
