Nicholas Briggs is a British actor and writer, predominantly associated with the BBC science fiction television series Doctor Who and its various spin-offs. Some of Briggs' earliest Doctor Who-related work was as host of The Myth Makers, a series of made-for-video documentaries produced in the 1980s and 1990s by Reeltime Pictures in which Briggs interviews many of the actors and writers involved in the series. When Reeltime expanded into producing original dramas, Briggs wrote some stories and acted in others, beginning with War Time, the first unofficial Doctor Who spin-off, and Myth Runner, a parody of Blade Runner showcasing bloopers from the Myth Makers series built around a loose storyline featuring Briggs as a down on his luck private detective in the near future. He wrote and appeared in several made-for-video dramas by BBV, including the third of the Stranger stories, In Memory Alone opposite former Doctor Who stars Colin Baker and Nicola Bryant. He also wrote and appeared in a non-Stranger BBV production called The Airzone Solution (1993) and directed a documentary film, Stranger than Fiction (1994). Briggs has directed many of the Big Finish Productions audio plays, and has provided Dalek, Cybermen, and other alien voices in several of those as well. He has also written and directed the Dalek Empire and Cyberman audio plays for Big Finish. In 2006, Briggs took over from Gary Russell as executive producer of the Big Finish Doctor Who audio range. Briggs co-wrote a Doctor Who book called The Dalek Survival Guide. Since Doctor Who returned to television in 2005, Briggs has provided the voices for several monsters, most notably the Daleks and the Cybermen. Briggs also voiced the Nestene Consciousness in the 2005 episode "Rose", and recorded a voice for the Jagrafess in the 2005 episode "The Long Game"; however, this was not used in the final episode because it was too similar to the voice of the Nestene Consciousness. He also provided the voices for the Judoon in both the 2007 and 2008 series. On 9 July 2009, Briggs made his first appearance in the Doctor Who spin-off Torchwood in the serial Children of Earth, playing Deputy Prime Minister and Foreign Secretary Rick Yates.

Mark Gatiss (born 17 October 1966) is an English actor, screenwriter and novelist. He is best known as a member of the comedy team The League of Gentlemen, and has both written for and acted in the TV series Doctor Who and Sherlock. Fulfilling a lifelong dream, Gatiss has written three episodes for the 2005-revived BBC television series Doctor Who. His first, "The Unquiet Dead", aired on 9 April 2005; the second, "The Idiot's Lantern", aired on 27 May 2006 as part of the second series. In addition, Gatiss was the narrator for the 2006 season of documentary series Doctor Who Confidential, additionally appearing as an on-screen presenter in the edition devoted to his episode. Gatiss did not contribute a script to the third series, but appeared in the episode "The Lazarus Experiment", as Professor Lazarus. After his submitted script for the fourth series, involving Nazis and the British Museum, was replaced at the last minute with "The Fires of Pompeii", he eventually returned to the programme in 2010, writing the (also World War II-themed) episode "Victory of the Daleks" for the fifth series, in which he also appears uncredited as the voice of "Danny Boy". It has also been confirmed that Gatiss will be writing an episode for the 2011 season of Doctor Who, although details about the story are yet to be revealed.[19] Gatiss wrote an episode of Sherlock, a modern day Sherlock Holmes series co-produced by him and Steven Moffat. The unaired pilot was shot in January 2009 and a full series was commissioned. This was aired in August 2010 and consisted of 3 episodes. Gatiss also starred in these as Holmes' older brother Mycroft. A second series has been confirmed, but dates have yet to be decided, since both Gatiss and Moffatt have additional commitments.[20] Gatiss also wrote and performed the comedy sketches The Web of Caves, The Kidnappers and The Pitch of Fear for the BBC's "Doctor Who Night" in 1999 with Little Britain's David Walliams, and played the Master in the Doctor Who Unbound play Sympathy for the Devil under the name "Sam Kisgart", a pseudonym he later used for a column in Doctor Who Magazine. (The pseudonym is an anagram of "Mark Gatiss", a nod to Anthony Ainley, who was sometimes credited under an anagram to conceal the Master's identity from the viewers.) The pseudonym was used again in television listings magazines when he appeared in episode four of Psychoville, so as not to spoil his surprise appearance in advance. In mainstream print, Gatiss is responsible for an acclaimed biography of the film director James Whale. His first non-Doctor Who novel, The Vesuvius Club, was published in 2004, for which he was nominated in the category of Best Newcomer in the 2006 British Book Awards. A follow up, The Devil in Amber, was released on 6 November 2006. It transports the main character, Lucifer Box, from the Edwardian era in the first book to the roaring Twenties/Thirties. A third and final Lucifer Box novel, Black Butterfly, was published on 3 November 2008 by Simon & Schuster.[21] In this the protagonist finds himself serving Queen Elizabeth II, in the Cold War era. Gatiss also wrote, co-produced and appeared in Crooked House, a ghost story that was broadcast on BBC Four during Christmas 2008.

Clayton Hickman has had a wide-ranging impact upon the Doctor Who franchise. The longest-serving editor of Doctor Who Magazine, he was the dominant editorial voice on the publication for most of the first decade of the 21st century. He was officially credited as assistant editor on issue #296 in 2000 and remained at that post until taking over the full editorial reins from Alan Barnes with issue #314 in 2002. He remained the magazine's editor until issue #386 in 2007. One of his most notable achievements was the magazine's radical redesign at the start of the BBC Wales version of Doctor Who. As a part of his duties, he was also one of the key creatives on the comic strip, primarily during the Eighth, Ninth and Tenth Doctors' runs. Indeed, he co-wrote the first of the "new series" comic strips, The Love Invasion, with frequent collaborator, Gareth Roberts. He also established the tradition of Panini publishing an annual, first with the 2006 Doctor Who Annual and later with Doctor Who Storybook line that began in 2007. He was instrumental to Panini's digital restoration and reprinting of virtually their entire catalogue of comic strips in graphic novel format, beginning with The Iron Legion. He also shepherded the creation of yet a fourth Panini series, Doctor Who Magazine Special Edition, whose issues took in-depth looks at particular Doctor Who topics. Hickman had an important role to play in the production of Big Finish Productions' audio dramas. Not only did he design many of the company's CD covers, he co-wrote the scripts of The One Doctor and Bang-Bang-A-Boom! with Roberts. He designed some of the Region 2 covers for Doctor Who DVD releases. As of 2010, Hickman's writing credits for the televised Doctor Who universe have been confined to The Sarah Jane Adventures. With Gareth Roberts, he co-wrote the Comic Relief sketch, From Raxacoricofallapatorius With Love and co-wrote the finale to Series 4. Hickman's long experience with the franchise, coupled with his articulate irreverence, made him a frequent interviewee on Doctor Who Confidential, a celebrity judge on Totally Doctor Who and a regular contributor to Doctor Who DVD documentaries. He also provided the voice of the Daleks on AUDIO: The Time of the Daleks.
