In the sequel to the original, Curtis and Pleasence reprised their roles, with Carpenter and Hill also returning to write and produce. Though Castle and Moran returned for flashback scenes, Dick Warlock took over the role of Michael.
The movie picks up where Halloween concludes, with Michael disappearing and his sister Laurie narrowly escaping his murderous attacks. While Laurie recovers in the hospital, Loomis continues to search for his former patient.
Originally, Halloween II was intended to be the last chapter of the Halloween series to revolve around Michael Myers (spoiler alert: he is seemingly killed by Laurie and Loomis in the end), but Michael would make his return again seven years later.
