The HBO series 'It: Welcome to Derry' employed a range of old-school horror techniques to create unsettling visuals. The show's visual effects supervisor, Daryl Sawchuk, notes that the series was treated as an eight-hour feature film, allowing for a more immersive experience. This approach enabled the creators to push the boundaries of traditional horror techniques. The use of puppeteered characters, such as the Mutant Baby, and other visual effects, like the Mother Thing, added to the series' eerie atmosphere.
