Review: Shamefully, before I saw this film, I was unfamiliar with Helena Bonham Carter.I had to do some research, in order to assure myself she wasn't actually afflicted, as was her character, with (well?), what she was afflicted with. I was in absolute awe of this beautiful lady. She pulled it of flawlessly.Who would have thought that sexually explicit circumstances involving the final wants, and needs, of a unique young lady, could be interpreted as tender, and romantic? Well, they can be, when the right performers present them in the proper manner, as they did in this wonderful movie. I forgot to mention how dynamically beautiful Miss Carter looked in this movie. I have often said she was the most beautiful creature to have ever graced the face of our earth, but she seemed to have out done herself in this particular movie.I hope any of you who watch this movie enjoy it as much as I did. Thank you for letting me express my opinion. Question: is it a positive review?

Review: Young beautiful Eva (Hedy Lamarr) marries an older man (Zvonimir Rogoz). Unfortunately he can't satisfy her sexually and ignores her. Frustrated she goes home and plans to get a divorce. Then, one day, she's skinny dipping in a lake in the middle of the woods. Her horse gallops off with her clothes...and she runs after it! She meets young and very handsome Adam (Aribert Mog). They make love and she realizes this is the man she wants.ENDING SPOILER!!!! Naturally, since this was made in 1933, she has to be punished for her sin so it leads to a tragic finale. END OF ENDING SPOILER!!!!This horrified people in 1933 but it's pretty tame by today's standards. Lamarr's nude swim shows nothing and when she runs after the horse totally nude, it's either shown in extreme long shot or is covered by branches and such. There's only a few minor shots of her breasts. Also when she has sex with Mog, nothing is shown but her face but you see her achieving an orgasm. These scene were considered pretty extreme in their day and were cut out completely of the American release. Now today they're back in. This film would get by with a PG-13 easily now.Shock episodes aside this is just OK. It is beautifully filmed and there's next to no dialogue. Except for the music score this could be a silent picture. Luckily all the actors are good--Lamarr and Mog especially and they're so attractive that they just take your breath away watching them. Also the sequence where they make love is easily one of the most beautifully shot and acted sequences I've ever seen in a movie. The scenes with the sexual symbolism (there's quite a few of them) are unfortunately pretty obvious today. I actually started to giggle during one!So, great direction, beautiful imagery, attractive actors, good acting all around--but I wasn't exactly bowled over by it. I found the movie slow-moving (beautiful imagery does not make a picture for me), somewhat dull, obvious, static and had a negative ending. I can live with the ending but it doesn't excuse the other problems I had with it. Also the final sequence is REALLY strange--and out of place. So I admire this film more than anything else. It was well-done and I'd recommend it but with caution. Many people seem to love this movie so I'm in the minority. Use your own judgment. Question: is it a positive review?

Review: Still the definitive program about the Second World War, The World At War isn't just long, but also very informative. The series contains 26 episodes (each episode lasts for about 45 min.), and includes the events leading up to and following in the wake of the war. Most episodes are about the war in Europe, and there are several episodes about the war in the Pacific. Other episodes include information about the wars in Africa, Burma, the Atlantic and the home fronts of Germany, Great Britain, United States and Soviet Union. There is one episode that's dedicated to the Holocaust. The series starts off with the episode A New Germany (1933-1939), and tells about the rise of the Nazis in Germany and German territorial gains prior to the outbreak of war. The series ends with the episode Remember; the war's influence in a post-war world. Remember is a fitting episode to end this great program. Every episode begins with a short introduction and then with opening credits. The credits are accompanied by a powerful music theme. There are many fitting music pieces throughout the series. Each episode is like a mini-film. The footage is fantastic, and so is the way it was put together. In addition, some of the footage is in color. The information included also makes the episodes memorable and entertaining.The series was produced by Jeremy Isaacs for Thames Television (UK). Commissioned in 1969, it took four years to produce, such was the depth of its research. The series was narrated by Laurence Olivier (one of the most famous and revered actors of the 20th century). The series interviewed leading members of the Allied and Axis campaigns, including eyewitness accounts by civilians, enlisted men, officers and politicians, amongst them Albert Speer, Karl Donitz, Jimmy Stewart, Bill Mauldin, Curtis LeMay, Lord Mountbatten, Alger Hiss, Toshikazu Kase, Arthur Harris, Charles Sweeney, Paul Tibbets, Traudl Junge and historian Stephen Ambrose. Jeremy Isaacs says in "The Making of The World at War" that he sought to interview, not necessarily the surviving big names, but their aides and assistants. The most difficult subject to locate and persuade to be interviewed, according to Isaacs, was Heinrich Himmler's adjutant, Karl Wolff. The latter admitted to witnessing a large-scale execution in Himmler's presence.The World At War is often considered to be the definitive television history of the Second World War. Some consider it the finest example of the documentary form. In a list of the 100 Greatest British Television Programmes drawn up by the British Film Institute in 2000, voted for by industry professionals, The World at War ranked 19th. The program has everything that the viewer needs to know about the war. After watching a few episodes I liked the series so much that I tried to watch the remaining episodes one after the other. I've seen some of them several times. There are two other great documentary series that I know of that may be of interest to the viewer. One is called The Great War (1964) that's about World War I. The other is called Cold War (1998) that's about the Cold War obviously. Question: is it a negative review?
