The filming for Tom Cruise’s first project with United Artists has not been spared its share of incidents: several extras were injured this weekend after falling off a truck and required medical attention.

Filming for the anticipated first movie to be produced by historical film studio United Artists (under the watchful eye of Hollywood star Tom Cruise and his longtime producing partner Paula Wagner) was temporarily interrupted when an accident occurred Sunday evening.

United Artists said 10 extras were lightly injured after falling off a truck that was driving at low speed, while scenes were being filmed around the Finance Ministry in Berlin (once the Nazis' aviation ministry.)

“No one suffered anything more serious than cuts and bruises, though one of the extras was kept in the hospital overnight for observation,” a statement released Monday from United Artists said.

Police said 11 persons had been injured and that the injuries were indeed not serious. Authorities will investigate whether this is a case of negligent bodily harm, according to Berlin police spokesperson Martin Grosse.

Grosse specified that Tom Cruise, who stars in the movie and is one of the producers, was not there. “Tom Cruise was not there and the film director also wasn't there,” Grosse said.

Sunday’s accident will not hinder the production schedule, the statement from United Artists said.

It is expected that the truck involved in the accident will be examined to determine whether there was a mechanical defect.

Filming for “Valkyrie” began in mid-July. Tom Cruise, 45, has been staying in Berlin with his wife, actress Katie Holmes, 28, and their 14-month-old daughter, Suri.

Cruise stars in “Valkyrie” as Colonel Claus von Stauffenberg, a German nobleman who opposed Hitler’s policy and plotted to eliminate him. Considered one of Germany’s few heroes of the Nazi era, he was executed when his plan to assassinate Hitler failed.

Cruise’s casting as the defiant aristocratic officer has sparked a controversy in Germany. Cruise is famous for being a Scientologist and the German government does not approve of Scientology, thus considering Cruise an inappropriate choice for portraying the colonel.

Officials initially opposed filming in historical locations in Berlin's government district.

“Valkyrie,” whose title is inspired by the codename given to the assassination plot, Operation Valkyrie, is slated for a 2008 release. It is directed by Bryan Singer and co-stars Kenneth Branagh
