In the death scene, Bonnie and Clyde are showered with bullets. The scene goes back and forth between regular motion and slow motion, making the bodies appear to dance (a trick the editor learned from watching Akira Kurosawa's Seven Samurai). Also, the last shot is filmed from within the car, as if Bonnie is looking out the window. This ending changed the way Hollywood tackled violence in films, inspiring filmmakers to up the amount of blood, bullets and gore.
In real life, the coroner taking care of Bonnie and Clyde reported 17 bullet holes in Clyde's body and 26 in Bonnie's, making it difficult to embalm their bodies. The fluid would leak from the holes.
