For the 2001 Christmas special and thereafter, Caroline Quentin declined to appear, and so a second supporting role was introduced, theatrical agent Carla Borrego, played by Julia Sawalha. After her first appearance, the character married TV producer Brendan Baxter (Adrian Edmondson), and she became a TV presenter. A third supporting role was introduced when the show returned in 2009 after a five-year hiatus. From "The Grinning Man" onwards, Creek was assisted by online paranormal investigator Joey Ross, played by Sheridan Smith. As Smith was unable to appear in the fifth series due to other commitments, she was replaced by Sarah Alexander as Creek's wife and newest sidekick.
