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.
Everyone Is Jesus in Purgatory: In his review of Glory, Civil War historian James R. McPherson suggested that the scene where Shaw is practicing his sword technique to slice up watermelons symbolized a desire by the filmmakers to destroy negative stereotypes of African-Americans. Director Edward Zwick, however, said that they just used watermelons in that scene because pumpkins were out of season at the time of filming.
Special Effects Failure: As Shaw is falling after he has been shot dead, viewers can make out the squib line tied to one of his legs. Also less apparent is the appearance of a tourist's head in the background of the scene where Rawlins declares a "Year of Jubilee". Both of these are pointed by director Edward Zwick during the course of his DVD Commentary.
