Hunnamplays the haunting serial killerin the third season ofRyan Murphyand Ian Brennans Netflix horror anthology series, and the official and full trailer (below) lives up to the streamer hyping this season as the most harrowing yet in the Monster franchise. All episodes release Oct. 3.

Geins horrific legacy inspiredPsycho,The Texas Chain Saw MassacreandThe Silence of the Lambs, becoming the blueprint for modern horror. The first footage had explored Geins house-of-horrors home being investigated by police who were so disturbed, they could barely go through what they found, and ended with a haunting conversation between Gein and his mother, who is played by Laurie Metcalf. The official trailer now exposes Geins nightmarish proclivities, as he is seen committing several murders and literally trying on (and dancing around in) the skins of his victims. Hunnam also reveals the mannerisms and voice he took on to play Gein, which he previously spoke about when discussing his research for the part.

Monster: The Ed Gein Story follows the first two Monster seasons, The Jeffrey DahmerStoryand the Lyle andErik MenendezStory,respectively. Each cycle of thefranchise tackles a different true-crime story, following the massive success of the series 2022 debut.

Gein is the serial murderer and body snatcher often referred to as the Butcher of Plainfield who gained notoriety in the 1950s for his crimes.
