Criminal is a series of four Netflix police procedural anthology TV series set in four countries. The four series are Criminal: France, Criminal: Germany, Criminal: Spain, and Criminal: UK. The series was devised by its showrunners George Kay and Jim Field Smith, and produced by their company Idiotlamp Productions. Although the showrunners are based in the UK, each of the local three-part series is written and performed in that country's native language by native actors, but all four individual local series were shot on the same set in Madrid, Spain. All four series were released simultaneously in September 2019. A second series of Criminal: UK, consisting of four episodes, was released on 16 September 2020.
