The Fourth Doctor himself, Tom Baker, has signed up for a series of audio adventures for Big Finish.

The first season of six single-disc releases will be released in January 2012, while a second season is to follow at a later date.

Though few plot details have been released as of yet, Big Finish have confirmed the companions in the plays will be Louise Jameson as Leela and Mary Tamm as Romana. Oh, and happily “some familiar monstrous faces from the past” will also be popping up.

Big Finish’s executive producer Jason Haigh-Ellery says: "I am delighted that Tom will be joining the Big Finish audio adventures of Doctor Who. As a small child, I remember how charismatic and engaging his performance was each Saturday tea time – and we are all looking forward to recreating that era again."
