6. Bullet Reconstruction (The Dark Knight)
http://www.youtube.com/watch?v=30Ddn5e598Y Christopher Nolan's The Dark Knight wasn't simply an iconic film which gave our beloved Cape Crusader, but an astounding villain to compete against in Heath Leder's the Joker. Unfortunately for fanboys worldwide, even this movie can't avoid being guilty of bad science. There's a sequence in which Bruce Wayne and Lucius Fox go to the laboratories of Wayne Manor to re-create moments of gunfire. Using a high-tech 3D computer algorithm, the Dark Knight and Mr. Fox reconstruct bullet fragments in order to obtain a fingerprint. Not only is the technology used here not really a thing, but it seems unlikely that the villains of the film would just assume that Batman has these devices available to him.
