One of the four types of deceptions in a romantic comedy is the Magic Potion Deception. Magic potion deceptions in romantic comedies like "Splash," "Mannequin," and "Penelope" offer love and acceptance through the lens of magical realism. Be it a mermaid, a mannequin or a cursed woman, each film cleverly uses the magic potion deception to challenge characters to look beyond the surface, leading to comedic escapades and touching revelations that celebrate the transformative power of love and the importance of embracing one's true essence.
