Tatort, which has run for 40 years and is now a national institution, is produced in 15 different regional versions (a Bavarian Tatort, a Saxon Tatort, and so on), all taking turns in the show’s time slot. “Each Tatort makes something of its regional roots, with actors speaking in local accents, solving crimes based on local imbroglios; and Germans talk about their favorite Tatort roughly the way they do about their local soccer teams.”
