History Trivia / DoctorWhoS18E3FullCircle

** In Andrew Smith's original outline, the adventure involved the TARDIS landing on the planet Alzarius, where monstrous Marshmen rise from the swamps during the time of Mistfall. As the Doctor and Romana explore, a space freighter crashlands on Alzarius, and the time travellers must help its crew repair the ship while fending off the Marshmen and gigantic cave-dwelling spiders. They are aided by a young Marshchild, who has been rejected by the rest of her kind due to her pacifist nature. In the end, the Marshchild sacrifices herself to keep the Doctor and Romana safe until the mists vanish and the Marshmen retreat to the swamps. The Marshchild became Adric.
** A power struggle amongst the Outlers between Varsh and Tylos was eliminated from the script, while a Marshchild character was reintroduced, replacing a mature Marshwoman.

** Varsh was originally named Arfrus.

* CastTheRunnerUp: Bernard Padden auditioned for Adric, but lost out because of his strong Northern accent. (At the time, it was felt that an extraterrestrial character should not have a distinctive accent -- apparently [[Creator/ChristopherEccleston not all planets had a North]] back then.) Instead, he appeared as Tylos.
