Adopt a flawless Danish accent (or German, Australian, Italian, Polish, Irish or Bronx)? No problem. Channel Margaret Thatcher or Julia Child? Done. Sing and dance? Sure. The word “chameleon” doesn’t quite describe Meryl Streep, who is always recognizable even with no hair (One True Thing), no teeth (Ironweed) and no conditioner (The French Lieutenant’s Woman). Rather, she’s a vehicle through which characters emerge—we can see her, but we forget she’s there. Check out our photo gallery for her latest buzz-generating manifestation—as the witch in Into the Woods, in theaters Christmas Day—along with the full cast of characters that have made Streep one of the greatest actors of all time.
