Lynn Gardner voiced the Announcer in the Doctor Who television story Dragonfire.
Gardner was originally cast as Ray in Delta and the Bannermen. However, she suffered an accident while practising riding a motor scooter for the story and injured her leg. As a result, Gardner had to withdraw but was still paid as she was already contracted. Later, as a consolation, she was offered the less strenuous voice-over part on Dragonfire. (TCH 43)
