These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Adaptation Displacement: The film is adapted from a little-known book by Thomas Hauser, The Execution of Charles Horman: An American Sacrifice.
Harsher in Hindsight: Years after the film's release, with the advent of advanced DNA testing, it was determined that the body shipped back to the United States (as seen in the film's final image) was NOT that of Charles Horman.
