In Mrs. Doubtfire (1993), Robin Williams’ transformation looked like a piece of cake, courtesy of a hilarious montage of character changes. The actual process, however, took nearly five hours every day with eight different stages of application. The mask was designed in pieces to allow for multiple facial expressions and then blended to look seamless. The age spots and wrinkles were applied by hand every session. And don’t worry about the mask that got crushed by the truck – it was a prop. The impressive result won an Oscar for Best Makeup.
