Has Denmark run out of TV actors?

First Ulrik Strange, Sarah Lund's sidekick from The Killing, turned up in Borgen as glamorous political husband Philip Christensen. Then weedy news editor Torben Friis was revealed to be Lund's previous sidekick, Jan Meyer. It seemed a bit odd that the cast of The Killing had muscled their way into Denmark's answer to The West Wing, but everyone was too busy concentrating on the subtitles and light fittings to think about it too much – even when dear old Theis suddenly appeared, disguised in a suit and glasses. It was just another coincidence. But now? Now I'm worried that Denmark has run out of actors. ITV3 is the unlikely home of the latest Danish crime drama import, Those Who Kill. And anyone tuning in for the first episode tonight will find that the old Forbrydelsen gang are out in force again. The cold eyes of the Killing II's Skogaard peer from the screen. Cries of "Troels!" will ring out as the show's police chief is revealed. His old girlfriend, Rie Skovgaard, even makes a comeback in later episodes. Even the Borgen crew are getting in on the act: the slightly-incapable-but-actually-rather-great Sanne pops up before long. There's no sign, however, of her remarkable ex-boss, Birgitte Nyborg. Denmark might be running short of supporting actors but its supply of no-nonsense female leads shows no sign of drying up – Those Who Kill gives us another detective happy to run about in the dark with a torch, Katrina Ries Jensen. Sadly, she is no match for Sarah Lund: as this new import proves, even if they share some of the same actors, not every subtitled Danish crime drama has quite the class of Forbrydelsen.
