The American Adventure is a animatronic show in World Showcase - American Adventure at Epcot. While it's not the best, it is also recommended.
This 30-minute show is Disney’s rendition of American history as told by Audio-Animatronic versions of Mark Twain and Ben Franklin. Behind the “actors” is an immense rear-projection screen upon which images are interwoven with the animatronic action on stage. You have to walk up to the second floor of the building to reach the theater, because the show’s various scenes are kept on separate stages which are stored underneath the audience’s seats. The background images for each scene also reflect the technology of the time period: pilgrims and colonialists use paintings, the Civil War uses photographs, and World War I and so on use moving pictures. The show’s finale is a performance of “Golden Dream,” with music by Bob Moline and lyrics by Randy Bright, presented over a montage of what’s happened in American history since World War II.
