* ActorAllusion: Director Allusion - two girls in the bar are called Film/ThelmaAndLouise, which was directed by Ridley Scott.
* CowboyBebopAtHisComputer: Often in reviews, its stated that Jordan is attempting to join the Navy [=SEALs=]. However, in the film, she's trying to join a fictional Navy special operations team. Although, this is understandable, since the ''Combined Reconnaissance Team'' is [[{{Expy}} all too similar]] to the [=SEALs=]. The CRT is fictional, but many in the movie's universe refer to it as a SEAL Team, when in fact it is a combined arms spec ops unit that is made up mostly of [=SEALs=]. It's more an expy of the NSW Development Group (known as Team 6) than anything.
* DyeingForYourArt: Demi Moore buzzed her hair down to the scalp on camera, and worked out religiously to simulate the effects of going through combat training.
* EnforcedMethodActing: Most of the cast endured a boot camp to prepare for their roles. Viggo Mortensen however prepared on his own for months, in order to drum up a natural feeling of resentment among the soldiers.
* ExecutiveMeddling: An alternate ending was filmed in which [[spoiler: Jordan dies saving her Command Master Chief, and after her nationally televised funeral, three other women are shown reporting for CRT training]]. Even though this ending was more popular with test audiences, Disney execs chose the [[spoiler: happier ending]].
* IAmNotLeonardNimoy: Critics reacted to Jordan's character as if Demi Moore herself was going through what she did. Even on ThisVeryWiki, posts will refer to Jordan as Demi instead.
* IAmNotShazam: Demi Moore's character is not called Jane - she's Jordan O'Neil. 'GI Jane' is a nickname the press has for her.
* TheOtherMarty: Sam Rockwell was cast in an unspecified role and went to several rehearsals before he fell ill and had to be replaced.
* StarDerailingRole: This was the second under-performing film by Demi Moore, following ''Film/{{Striptease}}''. Both helped undermine her reputation, even though critics were pretty warm to her performance in this movie.
