Factual error: The movie takes place six years after the Vietnam War; mid to late 1970's (if the Three-Mile Island accident depicted in the film is supposed to be the actual accident, then it would be 1979; either way, it is sometime in the 1970's). The 20-dollar bills on the ground in New Orleans have Andrew Jackson's head in the large offset oval; a redesign of the currency that wasn't issued until 1998.
