Remember your journey is very important, young man. Therefore, you must travel with understanding as well as hope.
No sooner do we see Dodo running into the TARDIS than we see her running back out, into a jungle. In a spaceship. With an elephant. Wearing medieval clothing. (Dodo, not the elephant.) All watched over by a single-eyed humanoid creature. Paul Erickson and Lesley Scott waste no time getting the narrative going in “The Ark” (Story Production Code X), cutting from a lushly realized jungle setting to a futuristic control room, where a human judge wearing flip-flops sentences an unmindful technician to the punishment of seven hundred years of miniaturization for having failed to pay attention to a gauge. And did we mention the elephant?
“The Ark” exists in full on film, and happily so. Director Michael Imison and crew put together a quite lavish studio production, with wonderful high angle shots and detailed sets. There’s a panning shot that catches a moving snake on a tree for no more than half a second—even the elephant serves as little more than a quick prop to establish the profusion of Earth wildlife contained inside the giant generation ship our travellers find themselves on. I can only imagine the effort taken to get an elephant into the studio. Careful placement of trees and doors, accentuated by weaving camera work, further provides a sense of space and dimension, allowing the setting to become a character in its own right, one arguably more interesting than the other characters we meet in this four-episode story.
The Doctor quickly realizes that they have landed in no ordinary jungle, noting the odd combination of wildlife but mostly because, as he tells Steven, “it’s a jungle with a steel sky!” He further determines that the jungle floor vibrates slightly, but before he can explore further, he and his companions are captured by the human Guardians and their servants/slaves, the mute Monoids. A brief expository interlude fills in the gaps in our knowledge: the Earth is dying, roughly ten million years in the future, and being left “for the last time,” with all of Earth’s humans and a sampling of the wildlife on board a generation ship bound for the distant planet Refusis Two (a planet name one might expect from Terry Nation). Most of the humans and Monoids have been miniaturized for the generations-long journey, due to be completed in seven hundred years.
For so advanced an era, though, much knowledge has been lost through war and general decay. Rather than using some form of automation, the few non-miniaturized humans who serve as the giant ship’s crew rely on the Monoids as servants, even though preparing food takes little more effort than dropping a pill in water. They know little about the planet they’ve set their sights on colonizing, and frankly plan on annihilating the indigenous inhabitants on landing if they put up a fuss.
Not very advanced, then—more caretakers of tradition than technology—but still, all seems well and good. The Commander of the spaceship, which Dodo christens the Ark, seems content that the Doctor and friends mean no harm, despite some misgivings by the Deputy Commander, and our intrepid adventurers about to return to the TARDIS when Dodo sneezes. And causes a plague.
