Someone who has spent a lot of the past few months watching Law & Order UK on BBC America created a viral video that crossed out desktops today. It reminded us of how many British TV favorites have shown up in the series. The strong cast of regulars includes Ben Daniels (The State Within, Aristocrats), Freema Agyeman (Doctor Who), Harriet Walter (Little Dorrit, Dorothy L. Sayers Mysteries) and Bill Paterson (Wives & Daughters, Hard Times). But it’s just as much fun to see who will turn up in the episodes: Juliet Aubrey (Middlemarch, Primeval), Dervla Kirwan (Ballykissangel), Lesley Manville (Cranford), Eddie Marsan (Little Dorrit), Iain Glen (MI-5, Season 9). See how many stars you can spot.
