Early drafts of "The Five Doctors" (1983) featured a scene where Sarah Jane Smith encountered some Autons and is rescued by the Third Doctor, but it was dropped before filming for reasons of time and expense. A third appearance was planned for the aborted 1986 season during Colin Baker's tenure as the Doctor, but never materialized. Titled "Yellow Fever and How to Cure It", it was supposed to be set in Singapore, with appearances by the Rani and the Master. The story, which was to be scripted by the veteran writer Robert Holmes, only exists in outline form.
