Parker Finn’s Smile 2 expands the terrifying universe established in the hit first film, Smile. Smile 2 has plenty of scary scenes and new tricks up its sleeves to truly horrify its audience, but it also cleverly pays homage to one of the most iconic characters in horror history through the character of Paul Hudson. Smile 2‘s cast is led by pop star protagonist Skye Riley who, among other things, is being haunted by the death of her boyfriend, Paul Hudson. Hudson shows up several times throughout as one of the hallucinatory entities haunting Skye with that now iconic smile.
