Charlize Theron worked as a ballerina for 12 years, and showed her exquisite ballet skills in this film. Before filming, Charlize Theron received a four-month weight-loss and body-building training. Among them, gymnastics, trampoline, karate, judo, Brazilian martial arts Keipola and Israeli martial arts Krav Maga are all used to improve flexibility and strength. The unique architecture of the film was shot in Berlin and Potsdam, Germany, and most of the scenes about the government were shot in Tierheim Animal Shelter and Veterinary Center on the outskirts of Berlin. The artists in the crew once gave a charity performance in Berlin's Hard Rock Cafe, raising $3,000 for the animal shelter. Due to Charlize Theron's neck injury during training, the shooting was delayed by more than 65,438+0 months. After the injury, Charlize Theron insisted on doing all the stunts by herself, even though she was allowed to use body double in the contract. When promoting the film in 2003, Michael Rodriguez was the first choice to play Ian. Ian's story of catching flying insects with eyelashes is entirely from comics. The crew originally planned to shoot the film in Brasilia, but due to logistical factors, they were locked in Berlin, where most scenes were found, including the crematorium just built and the sewers that existed before World War II. Shot through-Sitandra's foot was pierced by glass, but disappeared in subsequent shots. A goof shot-there are some reused shots in the film.
