Zagreus (audio story)

 was the fiftieth monthly Doctor Who audio story produced by Big Finish Productions. To celebrate this story being Big Finish's fiftieth release and the 40th anniversary, the cast includes every single performer of a Doctor Who companion and Doctor to have worked with Big Finish at the time of production. Most perform roles different from their usual ones. As a result, this was the first audio story where Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann all appear together. To date, the only other audio dramas in which all four actors have appeared are AUDIO: The Four Doctors, which was released in 2010, and The Light at the End, which was released in 2013. Tom Baker appeared with them in the latter story.

 * Charley mentions that the Doctor escaped from Colditz Castle in October 1944. (AUDIO: Colditz)

 * Reverend Townsend's successor as the Cardington airbase's chaplain was Simon Murchford, who decided to become an Anglican minister to assuage the survivor's guilt which he suffered after the crash of the British airship R101 on 5 October 1930.
