Factual error: At a scene where Ron is in the Veteran's hospital doing physical therapy, it is supposed to be 1968, but the song playing is "American Pie." The song didn't come out until 1971.

Other: During the big protest march scene which is supposed to have taken place in the early '70's, one Vietnam vet who is sitting in a wheelchair is clearly wearing a pair of high top Reebok sneakers introduced in the late '80's.

Factual error: During the closing credits, two songs appear misspelled: "Hace un ano": The correct spelling is "Hace un año" - okay, not all keyboards have the Spanish "ñ" - , and Meleguena. This one is waaaay wrong: The correct spelling is Malagueña.
