Foyle's War

Creator Anthony Horowitz developed Foyle's War for ITV after the long-running series Inspector Morse ended in 2000.

Horowitz chose the surname Foyle because he wanted a name evoking the early 1940s, and thought of London's Foyles bookshop, once known for its archaic practices and its owner Christina Foyle; since Christopher was the nearest male equivalent to Christina, the detective was named Christopher Foyle.

Christopher Foyle, the real-life nephew of Christina Foyle who inherited control of the Foyles bookshop in 1999, made a cameo appearance in the episode 'Bad Blood', though the scene was cut from PBS broadcasts in the US.

St Just, a house on Croft Road in Hastings, was used as the filming location for Foyle's home.

Series seven was filmed in Ireland and London from late August to December 2012.

After ITV programming director Simon Shaps cancelled the series following series five, high viewing figures (a 28-percent audience share and 7.3 million viewers) for the presumed final episodes led ITV to enter negotiations that resulted in three additional series being commissioned.

The abrupt cancellation after series five forced Horowitz to discard scripts he had planned for most of 1943 and 1944, creating unusually large time jumps of nine months to a year between episodes, compared to gaps of a month at most in earlier series.

After the series' final cancellation, Horowitz wrote 'Foyle's Last Case', an exclusive two-part Christmas short story published in The Daily Mail on 22 and 23 December 2018.
