"Split" is a 2017 psychological horror thriller film written and directed by M. Night Shyamalan. The film is known for its suspenseful storytelling and connection to Shyamalan's earlier work. James McAvoy stars in the lead role, delivering a standout performance.
The story centers around Kevin Wendell Crumb, a man with dissociative identity disorder (DID) who has 23 different personalities. One of his personalities, known as "The Beast," becomes dominant and dangerous. After kidnapping three teenage girls, Casey Cooke (played by Anya Taylor-Joy) must navigate the different personalities to find a way to escape.
"Split" received positive reviews, with much praise directed towards McAvoy's versatile performance and Shyamalan's return to form as a filmmaker. The film also became notable for its unexpected connection to Shyamalan's earlier work, particularly his film "Unbreakable" (2000). This connection set the stage for the subsequent film, "Glass" (2019), which brought characters from both films together in a shared universe.
