The Emperor's New Clothes (2001)

The world's most powerful man is about to fight his greatest battle... between love and glory.

Napoleon, exiled, devises a plan to retake the throne. He'll swap places with commoner Eugene Lenormand, sneak into Paris, then Lenormand will reveal himself and Napoleon will regain his throne. Things don't go at all well; first, the journey proves more difficult than expected, but more disastrously, Lenormand enjoys himself too much to reveal the deception. Napoleon adjusts somewhat uneasily to the life of a commoner while waiting, while Lenormand gorges on rich food.
