Cold Blood is a long-standing soul- rock- jazz band founded by Larry Field in 1968 and originally based in the San Francisco East Bay area. They have also performed and recorded under the name "Lydia Pense and Cold Blood", due to the popularity of their lead singer, Lydia Pense.

"Cold Blood" is the ninth episode in the fifth series of British science fiction television series Doctor Who, which was first broadcast on 29 May 2010 on BBC One. It was written by Chris Chibnall and directed by Ashley Way. It is the second episode of a two-part story, the first episode being " The Hungry Earth", which features the return of the reptilian humanoid Silurians.

Continuing from the previous episode, alien time traveller the Doctor ( Matt Smith) and geologist Nasreen Chaudhry ( Meera Syal) have taken the TARDIS deep below the ground to the Silurian city where the Doctor's companion Amy Pond ( Karen Gillan), a local man named Mo (Alun Raglan), and Mo's son Elliot (Samuel Davies) are being held hostage. Meanwhile, above ground, Amy's fiancé Rory ( Arthur Darvill), Mo's wife Ambrose ( Nia Roberts), and Ambrose's father Tony ( Robert Pugh) keep watch over Alaya ( Neve McIntosh), a captured Silurian who is the key to freeing the hostages. When Ambrose kills Alaya, the Doctor attempts to prevent Alaya's sister Restac (McIntosh) from wiping out the human population as revenge by offering to share the planet with the Silurians.

Chibnall was elected by executive producers Steven Moffat and Piers Wenger to write a two-part episode about the return of the Silurians. Chibnall wanted "Cold Blood" in particular to be about the mistakes people make under pressure, and conflict that could come out of protecting a family. The episode is also connected to the series' story arc, as the crack in the universe returns at the end of the episode. "The Hungry Earth" and "Cold Blood" were filmed in October and November 2009, with scenes in "Cold Blood" shot in Llanwynno, Wales, Cardiff's Temple of Peace, Plantasia, and an array of locations and sets for parts of the Silurian city, which the production team did not want to look like a cave. The episode was watched by 7.49 million viewers in the United Kingdom and received mixed reviews from critics. Some reviewers were disappointed by the plot and characteristics of the Silurians, but the emotional ending was widely praised.

Cold Blood is a television series first broadcast on October 19, 2005, on ITV1. Three series of the show have been broadcast. The series stars Matthew Kelly as Brian Wicklow, a former serial killer who assists the police with investigations into murders and serial offenders. The series also features John Hannah as Jake Osborne and Jemma Redgrave as Detective Sergeant Granger.

Three official series of the show were produced: two stand-alone feature-length episodes and one final series comprising three individual stories. The show ceased production in 2007 following declining viewing figures; and the final episode was broadcast on January 3, 2008, to a mere 3.98m, a drop of more than 3 million viewers since the first episode.
