Based on the classic Lupin stories, this is a great movie ruined by Spielberg Syndrome. That is, where a movie ends, and then goes on for another 45 minutes.
There are great characters here, from the cabal of baddie royalists, to the seemingly immortal femme fatale. The story revolves around the stealing and re-stealing of three crucifexes which will somehow reveal the location of a king's treasure. If the movie stopped there, with all the plot threads the audience cared about wrapped up, the defeat of the bad guys, the discovery of the treasure, the resolution of the father issues, this would have been a 4 star movie. Instead it keeps going and going and going, as if the director had too much beloved source material and could not bare to cut any of it.
