Hall of Presidents is a animatronic show in Liberty Square at Walt Disney World's Magic Kingdom. It's worth seeing on a time-permitting basis.
In 1964, Walt Disney created his first Audio Animatronic human being — a talking, life-sized depiction of Abraham Lincoln for the New York Fair. Lincoln moved to Disneyland after the fair, where a modernized version of the animatronic continues to play, reciting excerpts from some of the Great Emancipator's most famous speeches.
For Walt Disney World, Disney's designers weren't satisfied with just building another Lincoln. Instead, they decided to create an attraction with all the United States Presidents, from George Washington on to the current occupant of the White House. So after every new President is inaugurated, the Hall of Presidents goes down for a refurbishment while Disney builds and installs a new President.
Still, Lincoln does most of the talking here, with the other Presidents nodding in the background. Starting during the Clinton administration, the current President also gets in a few words during the show. (Yes, Bill Clinton, George W. Bush, and Barack Obama each recorded their own parts for the show.) Keep your eyes peeled in the wait area, too, where you'll find mementos from past Presidents and First Ladies on display.
