Doctor Who has one-upped Snakes on a Plane.

On Saturday's all-new episode, "Dinosaurs on a Spaceship" (9/8c, BBC America), The Doctor, the Ponds and a few surprise passengers have a gargantuan task: save the precious cargo of dinosaurs on a spacecraft headed toward certain destruction.

Straddle a prehistoric lizard and go riding off into the galactic sunset, of course!
