 This title was worked into the script when Jack describes the idea of "flotsam and jetsam" falling through the Rift into Cardiff.The opening scene, involving the reanimation of a corpse in an alley at night, was adapted from a pitch written by Russell T Davies and Julie Gardner for a possible science fiction series called "Excalibur", devised before Davies became responsible for the 2005 revival of "Doctor Who".In "Kiss Kiss Bang Bang" Captain John Hart jokes about the name Torchwood and says it should have been named Excalibur.
