[Update January 9, 2012] The Bill may have been cancelled by ITV in 2010 after 27 years but Jack Meadows, played by Simon Rouse, is visiting Leipzig for a special of German crime drama SOKO Leipzig.
Filming of a 90-minute special of SOKO Leipzig called Die schwarze Witwe (The Black Widow) has started this week. Aired since 2001 on pubcaster ZDF, the "Krimi-Serie" SOKO Leipzig is one of the numerous spin-off series of the long-running SOKO 5113 (launched in 1978). Newly retired Jack Meadows (from The Bill) spends some time in Leipzig and pays a visit to his friend, SOKO boss Hajo Trautzschke (Andreas Schmidt-Schaller). When a face from an unsolved London case resurfaces in the German town.
In 2008-2009, ITV and ZDF joined forces for a crossover between SOKO Leipzig and The Bill called Entführung in London. Its director, Robert Del Maestro (who worked on both shows in several occasions), directs this new special due to be aired on ZDF in January 2012. From 1994 to 2006, German private channel RTL aired a local adaptation of The Bill called Die Wache. SOKO Leipzig is produced by UFA Fernsehproduktion.
