- Awesome, Dear Boy: Joseph Gordon-Levitt signed on to the film as soon as he saw the concept art for his Cobra Commander look, with his reaction being "I'm going to wear THAT?!"
- Backed by the Pentagon: The Army provided an Apache helicopter and extras for the opening fight.
- Contractual Obligation Project: Channing Tatum admitted that he was in the film as part of a three-picture deal and that he hated having to play Duke.
- Cowboy BeBop at His Computer: There are still people that saw this film wondering who "G.I. Joe" was. Now Hilarious in Hindsight as he's in the sequel!
- Creator Backlash: Channing Tatum has been extremely vocal with his dislike of the film.
- Creator Killer: Stephen Sommers was already on thin ice thanks to the failure of Van Helsing, but the negative reception to this film seemed to have done this to his career in the long run. He's only directed one film since and that made $1 million at the box office on a $27 million budget.
- Dyeing for Your Art: Sienna Miller (Baroness) is actually blonde, and Rachel Nichols (Scarlett) is a brunette. Although we do see Miller Pre-Baroness with blonde hair.
- Fake American
- The President of the United States is British. If you've played Command & Conquer: Red Alert 3, he's particularly eyebrow-raising.
- Try the Baroness (Sienna Miller was born in NYC, but raised in England). Which is pretty damn funny, given the character's origins in the comics.
- Snake Eyes is played by a Scot (though not only he's The Voiceless, but his young version in the flashback is American).
- Fake Nationality: Given Interchangeable Asian Cultures, the Japanese Storm Shadow is played by a Korean as an adult, and an American of Chinese descent as a teen.
- Certainly a case of Ability over Appearance, as Lee Byung-Hun was perfect in the role.
- Money, Dear Boy:
- Old Shame: For Sienna Miller, at least. Given only three cast members out of a large ensemble returned for the sequel, it's a safe bet she's not alone in this.
Working on something like GI Joe was horrendous. I just wanted to cut my throat every day.
- Channing Tatum hates the movie as well, and says the only reason he did it is because he would have been sued for breach of contract if he'd refused. (though Tatum admits he picked G.I. Joe because he was a fan of the franchise, which made him even more disappointed of the final product's quality)
- Christopher Eccleston revealed that he hated the film.
- Pragmatic Adaptation
- Cobra Commander was given a new look because of the fact that Sommers thought that giving him a hood (or even a ski mask) would make viewers think KKK member when they saw him. Nor would they justify a form-fitting, featureless steel face-mask, since they wanted Joseph Gordon-Levitt's face to be at least partly visible.
- Similarly, GI Joe becoming an international task force was done due to Paramount/Sommers wanting a high overseas box office pull for the film and thinking an all-US team of soldiers would not sell tickets outside North America.
- Though, both of these plot elements (Cobra Commander's face-mask and GI Joe being an American military team) are brought back for the sequel, and the box office justified both decisions.
- Promoted Fanboy: Marlon Wayans is an admitted fan.
- Throw It In!: Ripcord's helmet flashing holographic pictures of Scarlett. Originally, he was meant to be responding to the amount a virtual controls showing up in the HUD, but when it got to actually including the display in the visual effects department, they thought it'd be more amusing if it had her face popping up.
- What Could Have Been:
- Chris Evans, Matthew Fox, Mark Wahlberg and Sam Worthington were considered for Duke.
- Rapper Common was offered the role of Heavy Duty's cousin Roadblock, but film screenwriter, Stuart Beattie, chose Heavy Duty instead.
- The original script had Snake Eyes taking a vow of silence until he got revenge on Storm Shadow. When Storm Shadow is seemingly killed in their final fight, Snake Eyes would sigh out "finally." Longtime Joe comic book writer Larry Hama warned the producers that the fans would loathe the entire movie just for that one moment and it was dropped.
- Word of Dante: Brendan Fraser has said he thinks of his character, Sgt. Stone, as the descendant of Rick O'Connell.
