Catholic writer, Frank Cottrell Boyce has written an episode of the highly-anticipated new series of Doctor Who. He joins a group of writers, that includes Mark Gatiss, Steve Thompson, Gareth Roberts, in writing for the eight series of the hit television show.

The first episode of the new series of Doctor Who, which will see The Thick of It actor Peter Capaldi make his debut as the Doctor, airs on BBC One on August 23.
