8. Orson Welles - Citizen Kane
Aging makeup can be done well, or it can be done crazy badly, as anyone who's seen the epilogue of the last Harry Potter movie can attest. It's one thing to age up a character for one scene in the film, right at the end, because if it's reasonably decent people will pretty much leave it alone. It's quite another when, like in Citizen Kane, you're telling an extended story of one person throughout the span of their entire life. You can't fake your way through that. In addition to directing his feature film debut, Orson Welles plays Charles Foster Kane from a handsome, dashing man in his 20s to the sour, overweight man he became by his death. It was an extensive process that took at least seven hours, requiring Welles to start at two o'clock in the morning to be ready to start shooting at 9:00 am. He frequently clocked in sixteen hour days on set, even after a broken leg during film put him in a steel leg brace.
