# Doctor Who: The Fourth Doctor Adventures

In 2012, Big Finish Productions began producing audio dramas featuring Doctor Who's fourth Doctor, as portrayed by Tom Baker. Baker had previously declined to feature in any Big Finish releases, but after recording a trilogy of full cast audio boxsets for BBC Audiobooks, he decided to participate. This was also part of a spin off series of the Monthly range.
