1. Catherine Tregenna
Catherine Tregenna's name will ring a bell for Torchwood fans who have held her episodes in high regard. Her contributions to the Doctor Who spin off - Out of Time, Captain Jack Harkness, Meat and Adam - still stand out as some of the show's most iconic and defining moments and for the Doctor Who fans who have been waiting for her to bring some of the magic to the main show, your lucky might just be in. Recent rumours suggest that Catherine WILL be writing for Series 9 of Doctor Who after the coveted credit appeared on her CV. This intriguing development would make her the first female writer the show has signed since Helen Raynor in 2008. Her previous writing credits include EastEnders, Casualty and Law & Order: UK.
