An absolute delight. The funeral scene is one of the funniest on record, with one of Charles' wartime "buddies" sticking a pin into him to make sure he's dead. Both Grant and Hepburn excel in their roles, as does James Coburn as Tex Panthollow (I love that name), one of the wartime "buddies".
Let's face it, this movie is based on a flawed premise. The items into which Charles converted his wealth would suffer greatly in value if treated in the way indicated in the film, and I refuse to believe that their very unusual nature could be overlooked by the police (even the French police) and by everyone else who sees them.
But if you're prepared to overlook that, it is a delightful movie.
