It gives us an alternative World War II scenario, in which the Nazis managed to invade Britain. The debut writer/directors, brothers Ed (25) and Rory McHenry (22), have managed to entice an impressive array of stars into lending their voices to the film, including Ewan MacGregor, Rosamund Pike and Alan Cumming as a very camp Hitler.
The production is something of a family effort, as the brothers' dad, David McHenry is on production design (his credits include Love and Death on Long Island (1997) and Becoming Jane (2007) among much TV work), their two younger brothers Dom and Jack are helping with the puppets and mum, actress Maureen Bennett is often on set.
The movie is being shot at the Three Mills Studio in Bow, East London. When I visited the set last month, the crew were pretty busy blowing up Hadrian's Wall, the site of a spectacular battle between the Brits - led by MacGregor's Chris, a farmer with exceptionally large hands - and the Nazis, who are copying the invasion tactics of the Romans.Producer Karl Richards gave us a tour of the set and workshops, before we got the chance to sit down with the McHenry brothers. The sets are full of background details that will reward close watching, as famous London streets get a German-style makeover, whereas Scotland is portrayed as a mysterious, tribal nation that provides the backdrop to a showdown with the Nazis.
