* ActorSharedBackground: Flynn mentions being from Tennessee, which is also where Creator/SamuelLJackson grew up
* AwesomeDearBoy: Sam Jackson stated in interviews that he signed up just because of the title. He also threatened to quit when the producers wanted to rename it.
* FakeAmerican: The Australian Nathan Philips does an American accent to play Sean Jones.
* NotScreenedForCritics: [[Webcomic/PennyArcade It's not]] ''[[Webcomic/PennyArcade for]]'' [[Webcomic/PennyArcade them]]. The funny thing about this one is critical reaction was ''favorable''. The film actually holds a 68% critic rating on Rotten Tomatoes, but only 50% audience. Critic consensus was summed up as that "''Snakes on a Plane'' lives up to its title, featuring snakes on a plane. It isn't perfect, but then again, it doesn't need to be."
* PermanentPlaceholder: The movie was going to be renamed ''Pacific Air Flight 121'' for its release, but then its B-movie working title attracted a flurry of attention on the internet, and Creator/SamuelLJackson insisted that he'd only signed on to the film ''because'' of its ExactlyWhatItSaysOnTheTin title. The producers kept the working title to cash in on the online hype.
* TechnologyMarchesOn: When one of the passengers suggests they e-mail the herpetologist photos of the snakes they've killed so he can identify them, everyone else assumes they need to find a digital camera and computer. She holds up her smartphone and tells them it has both.
* ThrowItIn: The famous "I have had it..." line originated in a parody made in anticipation of the movie's release. The filmmakers added it into the final cut right before the release.
* UnintentionalPeriodPiece: The ability to take photos with a cell phone, and send them automatically to someone else was somewhat new at the time - and Mercedes is one of the few who can because she's implied to be a rich ValleyGirl. So, the scene where everyone has to be reminded that they can take digital photos of the snakes, and send to a snake expert can seem a bit jarring to younger fans.
* VindicatedByCable: It's not the kind of movie you should watch in a quiet theater. It's the type of movie you should watch at home with friends as you laugh and snark the hell out of it. The campiness of some of the [[{{Bowdlerization}} TV edits]] also helps boost the snark factor for some.
* WhatCouldHaveBeen:
** The initial script was 122 pages long, but got narrowed down to 103 pages over a period of four months.
** The first cut of the movie was going to be PG-13. But after fan interest on the internet, they did five days of re-shoots to add some R-rated content in.
