483: A look at Christopher H Bidmead's impact on Doctor Who

As the attentive among you might know, former Doctor Who script editor Christopher H. Bidmead died in early August. His work as a computer journalist directly informed his contributions to the show, not just as its script editor but also writer of serials such as Logopolis and Castrovalva, and Frontios.

This week, Christian Cawley and James McLean look back at Doctor Who's divisive Season 18. A new producer, an executive producer for the first time, a new script editor, and a lead actor on his way out of the door, it makes for interesting viewing, both as a show, and as a behind-the-scenes drama.

But central to all of that was Bidmead's new approach to the show, one that stripped back "The Tom Baker Show" and moved the adventures back into the realms of discovery and education.
