If you are a Monroe fan you are in for an hour-and-a-half of sheer enjoyment watching the ingenuous, irrepressible, sexy/innocent personality that Marilyn played so well. It's hard to take your eyes off her as feelings,thoughts,and reactions to events flow over her features in a feast of method acting, if that's what it is. The little story is entertaining in a shallow sort of way - there's something going on with mitteleuropa politics and family tensions but it hardly matters as the engine of the story is the wide-eyed little commoner dumped into an aristocratic environment, and everything that transpires in the short time-frame of her visit. The joke there is that she is always being farewelled but doesn't quite go, and reappears, always in the same dress. There's a fairly familiar thread contrasting sophisticated and corrupt Europe with the honest, down-to-earth representative of the New World. However the European side does provide the excuse for some great costumes and sumptuous interiors, making the film glamorous to watch. Laurence Olivier is reptilian and repulsive as the Grand Duke, which is fine except that we are supposed to believe that the Monroe character has fallen for him. This is not too credible! The direction is tight and effective, so kudos to Olivier for that. Sybil Thorndike is great fun as the Dowager Queen. It's Monroe's film however. I'd happily watch it any number of times.
