The only reason that Olivia de Havilland agreed to appear in this trifle must have been because it was going to be filmed in Paris where she was living at the time. On the positive side, there are great stars supporting de Havilland such as Edward Arnold, Adolphe Menjou and Myrna Loy, and they are very very good, as is the Star, but negatively speaking, the story has been done many times, but it could have been quite good, if a decent leading man had been engaged - there is no doubt John Forsythe was out of his depth, trying to compete with the players listed above. There were some bright moments of comedy, and it was good to see the Stars having a bit of a romp, but at times it is hard going. As lovely as she is, Olivia was too old for the part, but some of the shots of Paris helped a lot.
