There’s even a forum on the Internet Movie Database where members are trying to come up with a tagline for the film whose title is a tagline:

• Snakes On A Plane: “They’re not after the peanuts.”
• Snakes On A Plane: “Scared of heights? Scared of snakes? We put them together.”
• Snakes On A Plane: “This summer…snakes….are on….the plane….”
• Snakes On A Plane: “One Man. One Plane. Lots of Snakes.”
• Snakes On A Plane: “Pythons, Flying.”
• Snakes On A Plane: “You should’ve taken the train, ’cause there’s snakes on the plane.”
• Snakes On A Plane: “The Snakes love flying, but they HATE you.”
• [still of Samuel L. Jackson]: “Not on HIS plane.”
• Snakes On A Plane: “In 2006, the snakes are the terrorists.”
• Snakes On A Plane: “If you see just one ‘reptiles on a mode of transportation’ movie this year, make it Snakes on a Plane.”
• Snakes On A Plane: “Snakes. Plane.”
