This one of Sinatra's forgotten films but one of his best! It is a must have for anyone who is a Frank Sinatra fan or one who loves good quality drama/suspense/action flicks! Plot: This novel and subsequent 1960's film is without a doubt, a very interesting, highly improbable, but very entertaining idea concerning a group of individuals looking to make a big score for various selfish reasons. Initially looking for a sunken gold catch from an old wreck, a hired diver (Frank Sinatra) discovers and inspects a German U-Boat, unreported and in apparent good conditon found on the ocean floor. The plot turns in the film as the adventurers decide to go for the U-Boat and see if it can be used to heist gold that is currently afloat by robbing the Queen Mary on the high seas and using the sub as a weapon. The film is handled in a laid back manner. Sinatra plays a down and out semi-alcoholic adventurer, tired of war and all the rules. The film has atmosphere. There is a terrific Jazz score by none other than Duke Ellington. The underwater scenes are good and you are left with an overall good impression of an entertaining film. It is now almost forgotten among the Sinatra films but is actually one of his better acting performances as his personality works well with the character requirements. The book of course is different, as all films tend to lean to mandatory romance requirements and dramatic character confrontations and this includes the usual formula that British films seem to be able to do without. Recommended for an evening view. The dvd is encoded NTSC REGION O(playable on U.S. and Canada dvd players). The audio and video quality is EXCELLENT(rates 9 out of 10). Also, there is an interactive menu with scene selection for easy navigation through the dvd.INTERNATIONAL BUYERS DO NOT PAY UNTIL ADJUSTED INVOICE IS SENT REFLECTING ADJUSTED SHIPPING AND HANDLING FEES.
