This one scene is the most rememberable moment in the life of a saint, where she is put to death on a stake as a martyr. To be fair, the film does not actually show her burning but ends right before, but still - it tries to focus on this particular point of interest, maybe in order to bring a bit of shock to the audience at the time. It is well done, and the coloring is absolutely wonderful of the time(meaning it was probably colored this way later). Also, it seems like the movie in its short running time tries to press inn many events, like the trial, the judgment, and the execution at the same time, and understandably so - it has to tell a longer story, just like a picture. Only a few years later, in 1900, a longer movie of Joan Of Arc was made.
