“Whose Line Is It Anyway?” is the American adaptation of a British series sharing the same title, featuring many of the same talented performers. The show showcases some of the top improvisational comedians globally, such as Wayne Brady, Colin Mochrie, Ryan Stiles, and Drew Carey, with Drew hosting the majority of the episodes and Aisha Tyler taking over in the 2013 season. Every week, the core group of four improv comedians, along with a guest performer, engage in spontaneous “theatre sports,” creating hilarious scenes, quirky characters, and impromptu songs.
