7. GARY OLDMAN And WINSTON CHURCHILL
Gary Oldman won an Oscar for becoming Winston Churchill in Darkest Hour (2017). With heavy prosthetics, a bald cap, and Churchill’s signature scowl and cigar, Oldman was unrecognizable — until you realized he looked exactly like the wartime Prime Minister.
Oldman spent hours in the makeup chair daily and studied Churchill’s voice and mannerisms obsessively. The result was one of the most convincing political transformations ever put on screen.
