The Austin Powers franchise, a rollicking blend of comedy, espionage, and 60s nostalgia, almost had a fourquel, and the movie would have followed Austin Powers' Mini-Me. Created by Mike Myers, who also stars as the eponymous character, parodies the flamboyance and peculiarities of spy films, particularly the James Bond series. Central to its appeal is the quirky cast of characters, among which Mini-Me, portrayed by the late Verne Troyer, stands out as a fan favorite. Introduced in the second film, The Spy Who Shagged Me, Mini-Me is a comical mini version of the villain Dr. Evil, also played by Myers.
