The magical world of Harry Potter is filled with twists and turns. From the very beginning of the franchise, Harry (Daniel Radcliffe), Ron (Rupert Grint), and Hermione (Emma Watson) are thrust into a world where little is as it seems. Their first battle against evil brought about the twist that it wasn’t Professor Snape (Alan Rickman) after the Sorcerer’s Stone, but rather Professor Quirrell (Ian Hart). Then, in the Chamber of Secrets film, they face many twists, like the reveal that it was Ginny (Bonnie Wright) opening the chamber (with Voldemort’s help) and that Professor Lockhart (Kenneth Branagh) was a complete and utter fraud, never living out the fantastical adventures he made his living writing about. Later, there’s the reveal that Professor Moody (Brendan Gleeson) had been impersonated by Barty Crouch Jr. (David Tennant) throughout Goblet of Fire. However, the best twist in the entire series, in our humble opinion, is the truth about Peter Pettigrew (Timothy Spall) in Harry Potter and the Prisoner of Azkaban. Here’s why.
The most shocking twist in the Harry Potter franchise is the reveal that Peter Pettigrew is a rat, literally and figuratively.
