Quentin Tarantino is currently filming in Berlin

The star role is to be played by Brad Pitt. His character, Lieutenant Aldo Raine, leads a group of American-Jewish soldiers who are dropped into Nazi-occupied Europe to wreak revenge on the Germans and destroy their morale.

It is not just the scalping, or the carving of swastikas in foreheads, or the shooting of a German officer’s testicles, or the slow strangling scene – all shown with Tarantino’s customary love of detail – that is likely to upset the nation and its critics.

Three more join 'Inglorious Bastards'

Diane Kruger, Christoph Waltz and Paul Rust have joined the cast of Quentin Tarantino's Inglorious Bastards.

The trio join Brad Pitt, Eli Roth, Mike Myers and Michael Fassbender in the World War II drama, which focuses on a group of Jewish-American soldiers facing German armed forces in Nazi-occupied France.

Kruger (National Treasure) will play German actress Bridget Von Hammersmark, while Waltz will take the role of main antagonist Col. Hans Landa.

Inglorious Bastards begins production in Germany on October 13.

"Because the film takes place during the second World War, the agency will only hire extras who fit into this time visually," said the casting agency in an open call.

According to Tarantino's criteria, that means blonde men between the ages of 20 and 45 with military experience. Applicants with dyed hair, piercings, or a sun-bed orange glow are "taboo". Amputees will get a look-in. Hair must be long enough to be cut into a historically correct style - short sides, long top.

"So, once again, the Germans are the blonde, blue-eyed monsters," remarked one newspaper columnist sardonically.
