Dieter Langer, played by Louis Lovett, is a former German filmmaker who arrives in Killinaskully in the first episode with his partner Hans. Langer is a big fan of the singer Johnny Logan. After some difficulty in making their film, including the squashing of their equipment (and Hans) and Dieter's growing love for the local schoolteacher, Miss Fahy, Dieter switches trade to become a cheese vendor, a respectable trade which he hopes to use to woo his new love. He operates his "Dieter's Driven Deli" through the village from the back of his van. However, his cheese is responsible for causing some very strange dreams and the concepts of cheese and cheese-vending are used repeatedly for comic effect throughout the series. Still trying to come to terms with the strange ways of the locals, Dieter's desire to fit in is somewhat hampered by his innate belief in the importance of being earnest. Dieter ran against Cllr. Willie Power as the Green Party candidate in the 2005 Local Elections for the Killinaskully Local Area, he received 2 votes coming 2nd. His Father was a member of the German Parliament.
