Awesome, Dear Boy: 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.
Fake American: The Australian Nathan Philips does an American accent to play Sean Jones.
Not Screened for Critics: It's notforthem. 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."
Permanent Placeholder: 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 Samuel L. Jackson insisted that he'd only signed on to the film because of its Exactly What It Says on the Tin title. The producers kept the working title to cash in on the online hype.
Technology Marches On: 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.
Throw It In!: 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.
Unintentional Period Piece: 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 Valley Girl. 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.
Vindicated by Cable: 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 TV edits also helps boost the snark factor for some.
