The Golden Hour was an ITV drama series, first shown in 2005.

The title refers to the hour which is their critical time for handling emergencies. The series starred Richard Armitage and Lorna Fitzgerald.

Distant Shores is a dramedy first shown in the United Kingdom on ITV in January 2005. Like the similar fish out of water dramedies, Northern Exposure and Doc Martin, it focuses on the difficulties of an unwillingly-transplanted metropolitan doctor who is forced to adjust to a rural environment. The show's recurring cast is unusual for featuring major actors from three significant British franchises — Doctor Who, Blake's 7 and the James Bond film series. The programme itself is notable for being a rare example of a show to have an entire series shelved in its country of origin following the completion of post-production.

Red Cap is a British television drama series produced by Stormy Pictures for the BBC and broadcast on BBC One. Two series of six episodes each were produced following a feature length pilot. It featured the investigations of an Special Investigation Branch unit of the British Army based in Germany. Ostensibly the lead character was Sergeant Jo McDonagh, played by Tamzin Outhwaite, but the show was more of an ensemble piece, with several notable characters coming to prominence.

Judge John Deed is a British legal drama television series produced by the BBC in association with One-Eyed Dog for BBC One. It was created by G.F. Newman and stars Martin Shaw as Sir John Deed, a High Court judge who tries to seek real justice in the cases before him. It also stars Jenny Seagrove as the barrister Jo Mills, frequently the object of Deed's desire. A pilot episode was broadcast on 9 January 2001, followed by the first full series on 26 November 2001. The sixth and last series concluded on 18 January 2007. The programme then went on an indefinite break after Shaw became involved in another television programme, and he and Seagrove expressed a wish for the format of the series to change before they filmed new episodes. By 2009, the series had officially been cancelled. The six series produced make it the longest-running BBC legal drama. The factual accuracy of the series is often criticised by legal professionals and journalists; many of the decisions taken by Deed are unlikely to happen in a real court. The romanticised vision of the court system created by Newman caused a judge to issue a warning to a jury not to let the series influence their view of trials—referring to an episode where Deed flouts rules when called up for jury duty. Another episode led to complaints about biased and incorrect information about the MMR vaccine, leading the BBC to ban repeats of it in its original form. All six series have been released on DVD in the UK.
