Other mistake: After Bruno and Lutz had been arrested and are outside the police station arguing, in the background in the left corner, there is a gold Ford Mustang. Then as Lutz is walking away, the same gold Ford Mustang is seen driving in to park in that same place.
Other mistake: Throughout the movie, the subtitles for Bruno and Lutz translate everything from German to English. When Lutz carries Bruno on his back from the restaurant, he says "Herr Bruno", and the subtitle should say "Mr.Bruno" but says "Herr Bruno" still.
Answer: O.J. was played by twins Chibundu and Chigozie Orukwowu. No information is available on which scenes, if any, used some sort of double. As for the legal aspects, any major film production of this type will have legal experts on staff who will be more than capable of keeping the production safely within the law. So if you were planning on some righteous indignation, you're probably out of luck.
