Trivia: In the original script, every member of Forrest's platoon in Vietnam was supposed to have a low IQ. This was an experimental practice of the Army in the Vietnam War; the Army tried allowing soldiers with lower IQs to enlist, but put them all in platoons together. Because this led to so many discipline problems, the Army is not particularly proud of it and threatened not to work with the filmmakers at all if they left the platoon like that. As a result, only Forrest and Bubba are noticeably below average intelligence.
