Behind the scenes
At the time The Dæmons was produced, only two BBC networks were in operation, and the use of BBC 3 was intended to suggest a future timeframe (see UNIT dating controversy). In the real world, BBC Three launched in 2003 as a digital channel.
In the script for the ultimately unproduced 1993 film The Dark Dimension, a BBC3 news reporter named Tony McCabe is said to have been killed at Oxford Circus.
