The name Cormoran appears in Cornish folklore. He was a giant who lived in a cave on St. Michael's Mount off Cornwall's southern coast. 18ft tall he used the low tide to access the countryside and pillage the local community until he met his match in "Jack the Giant-Killer", a trapping pit and a mattock (pickaxe).
Strike's full name is Cormoran Blue Strike. Robin's is Robin Venetia Ellacott.
The office of Cormoran Strike is at 6 Denmark Street, which was also the "home base" for The Sex Pistols in 1976. Guitarist Steve Jones and bassist Glen Matlock temporarily lived upstairs.
In the "Troubled Blood" season, the role of current-day Janice Beattie is played by actress Anna Calder-Marshall, who is the real-life mother of actor Tom Burke (Cormoran Strike). (During the the 1970s scenes, younger Janice Beattie is played by Eliza Collings.)
This series was known as "Strike" when it aired in the U.K., but when it appeared on the U.S. airwaves its title was changed to "C. B. Strike." In 2017, Steve Greene reported for IndieWire that "the initials were added to the U.S. title to avoid confusion with "Strike Back," another series in the Cinemax 2018 lineup."
