Chop Suey, the Galactic Emperor!
To address the obvious: Robin Bland’s “The Brain of Morbius” (Story Production Code 4K) essentially recreates Shelley’s Frankenstein by way of Hollywood and Hammer Films, down to the dramatic lightning strikes, a stumbling Igor, a stitched-together monstrosity, and a torch-waving mob ushering in the monster’s end. But Bland—a pseudonym for long-time Doctor Who writer and script editor Terrance Dicks—spices up the otherwise tired tale with an impressive amount of ephemera regarding the Time Lords, adding interest to the surprisingly effective horror trappings on display.
The TARDIS materializes on the foggy planet Karn, guided there, according to the Doctor, by the Time Lords. He’s certain they’ve summoned him yet again to carry out their “dirty work,” and he refuses to help them, declaring, “I’m just going to sit here and do nothing.” Sarah attempts to get the Doctor interested in the plot at hand, remarking on all the crashed space ships nearby. Even the discovery of a headless alien, killed after escaping one of the wrecks, piques the Doctor’s interest only mildly. So Dicks whips up a sudden rainstorm to drive the time travellers to take shelter in a nearby structure, helpfully silhouetted on the horizon by blue lightning.
Inside, Solon and his hook-armed assistant Condo argue about the usefulness of the alien head Condo has recently procured using said hook; when the Doctor and Sarah arrive, seeking respite from the elements, Solon cannot help but comment upon the perfection of the Doctor’s head, a creepy comment that the Doctor takes in stride. The storm has knocked out the power in Solon’s abode, allowing these scenes to be shot with low lighting to amplify the ominous feeling. The audience already knows that Solon occupies the “mad scientist” role, leading to an odd sense of gullibility about the Doctor, who senses no danger when he and Sarah succumb to a drugged glass of wine.
Solon needs the Doctor’s “magnificent” cranium as a receptacle for the brain of Morbius, who formerly led the High Council of the Time Lords before being disintegrated for attempting to take over the galaxy, as often happens. But the Doctor is spirited off the operating table just before the head-removal procedure by the Sisterhood of Karn, who possess telekinetic powers. The red-robed novitiates aren’t trying to save the Doctor, though—they just want to be the ones to kill him…
