/* Attraction History */
In order to help set the various scenes which were to be depicted in the American Adventure, Imagineers initially wanted the attraction to have three hosts, with each host representing one of the centuries that America had existed for <ref name= "Korkis"/>. The three men chosen to guide guests through the story of America were Benjamin Franklin (18th century), Mark Twain (19th century), and Will Rogers (20th century). Although promoted in concept art by Disney <ref> http://progresscityusa.com/page/57/ </ref>, it was eventually decided that Will Rogers would not appear as one of the attraction's hosts (although he would appear in Audio Animatronic form in the 20th century scene), leaving the duo of Franklin and Twain as the sole narrators. This decision was made after Disney discovered that only 5 out of every 150 college students knew who Will Rogers was <ref name= "mouseplanet"/>, and they could not come to a consensus on a replacement. Bright later contemplated that the events of the 20th Century were too current to properly find a representative for <ref name= "mouseplanet"/>
The soundtrack for the American Adventure attraction was carefully created by composer Buddy Baker, who combined known, period specific songs, with new tunes written specifically for the attraction<ref name="vid2"/>. The music was then recorded by the Philadelphia Symphonic Orchestra before being mixed by engineer Bob Zalk <ref name="vid2"/>. In total, it took 18 months to mix the attraction's music, sound effects, and narration into the final score <ref name="vid1"/>.

Like the attraction's score, the artwork used in the American Adventure was specifically curated. Bright noted that they did not want to use "modern art" in the 18th and 19th century scenes <ref name="vid1"/>. Instead, Disney created new artwork that was stylized to look like it was from the correct period. In a similar fashion, photographs and motion pictures were not used until the scenes set in a time where these technologies had been invented <ref name="vid1"/>.
