I think it will be cheaper if it's a DVD, too. Maybe you can only buy the film in France, so shipping bills might be why the video's price is so high (if its being sold around the world).
Also, I remember watching a documentary drama a couple of years ago about Louis XVI, Marie- Antoinette and the court of Versailles. I found it very interesting...
