    There are so many scenes and shifts of teon, you're sure to like some of it.

    The Diamond Wizard (1954)

    A goofy, lighthearted, sprawling smuggling and international crime film. Yes, a contradiction. But boy are there zany aspects, like the low-tech high stakes attempts to make diamonds artificially. And the main characters are a British and an American agent both after the same charming American woman who is suddenly in town.

    You might enjoy this as a spoof (which it is not), or as pure camp (which it almost is). There are false foreign accents, talking and reading from criminal files, and constant back and forths (with literal winking) between the two men, who seem to work well together by doing the same thing at the same time.

    The odd thing is it's all kind of fun. It helps to have something else to do while watching--you won't miss any details, I think, since it putters along with easy to follow twists. The one scene to watch is the opening one, which gives away not only the very low budget limitations but also the basic characters involved. At other points there are little delights--like when the ship's whistle blows and we see the top of a ship, until the camera pulls back and you find we are looking at a model.

    So, if you don't mind a little silly romp with lots of scenes and a fairly ambitious scope, but with a frivolous and frankly low quality aspect, you might just like this. It's not awful, which is something. Parts of it look like they were shot in Frankenstein's castle. And there is a really terrific escalator scene that is almost worth it right there, toward the end, better than the movie deserves. And what are "pure galvanized iron filings" you might ask?

    International Intrigue!

    An American Treasury agent (Dennis O'Keefe) teams up with a Scotland Yard inspector (Philip Friend) to track down a group of thieves that are creating artificial diamonds out of sugar.

    This film seems to be a bit of a mystery. The BFI considers it lost, despite prints being readily available -- even on YouTube and Netflix. And then the director is a bit of a debate. Whether the print is the American or English one, the director name is switched. The film itself does not seem to be different in different prints.

    The plot is pretty good, and the idea of synthetic diamonds is interesting. One has to wonder... could synthetic diamonds be made so well that there would be no real chemical difference?

    Better than its current rating.

    IMDb Trivia: One of the "75 Most Wanted" films listed by the British Film Institute as "Missing, believed lost".

    I saw this film on Netflix, so apparently it is NOT lost--at least not any more.

    Dennis O'Keefe plays a Treasury Department agent who has been sent to Britain. This is because there may be an organization that has learned to produce perfect diamonds--ones that are so perfect it could destroy the market. The trail leads to a scientist--a scientist who has disappeared. Although the chances are ridiculous, the wanted man's daughter just happens to be a lady that the Treasury man was dating! He's afraid to tell her about everyone's suspicions about her father and he and Scotland Yard are baffled.

    This is a decent British version of film noir. While it's not quite as dark as many films in the genre, it is tough and violent and enjoyable. However, it does start off very slowly--so keep watching and don't give up on this one--it's worth it.

    If you do watch a couple things you should note. First, at one point in the film they talk about a remarkable fake diamond being produced in 1924. While it was believed in 1954 that this was true, apparently this was a hoax and that part isn't mentioned in the film. Second, when O'Keefe is chased by a truck he's knocked onto the cobblestones. Watch closely--these cobblestones bounce--revealing they are clearly props.

    The Diamond

    This has something of the "Rumpelstiltskin" to it, only it's not straw into gold, it's sugar into diamonds! "Dennison" (Dennis O'Keefe) is on the trail of some thieves who stole a fortune in US treasury bonds and are heading to London to do a deal with the gem fakers. His arrival sees him allied with "Insp. McClaren" (Philip Friend). This policeman is also working on a more sensitive case involving a nuclear scientist - and it just so happens that his daughter "Marline" (Margaret Sheridan) is wearing a brooch with one of the Wonka-jewels in it. As we discover who made it, the threads of the story start to come together - but who is pulling whose strings? It's a bit long and takes a while to get started, but once the wheels are in motion it's not a bad little thriller with some magical science (courtesy of Paul Hardtmuth) and a bit of menace from the usually reliable Francis de Wolff. It's all production line stuff with themes based on already well used, adequate acting and predictable plot-lines , but it is watchable enough.

    pretty typical except for the ending

    Likable actor Dennis O'Keefe made a couple of films in England in the '50s. "The Diamond Wizard" from 1954 is his baby all the way - he wrote the original story using a pseudonym (Jonathan Rix), he directed it, and he starred in it.

    O'Keefe plays Joe Dennison, a Treasury Dept. investigator in England trying to find a gang who stole a million dollars from a treasury vault and also killed his partner. One of the criminals apparently is in England to buy fake diamonds, though they realize he must be coming by ship because he as of yet isn't in England.

    The Scotland Yard inspector, McClaren, is working with Dennison on the case while also searching for Dr. Eric Miller, an atomic scientist who has disappeared. His daughter, who came to England to join her father, has a broach with phony diamonds, made by her father. So is he somehow involved with the thieves? This isn't a very interesting film until the end, where the location is an incredible castle. The whole end moves at a great pace, is suspenseful and atmospheric. I wish the whole movie had been that way. It's odd in the way it starts out as somewhat light, with both men competing for the missing man daughter's affections, and then has this big ending. Both lead actors, O'Keefe and Philip Friend (the inspector) are very charming.

    The story is derivative, but I love the idea of the phony diamonds -- there are so many of these today, and they even mention Moissan, whose product, Moissanite is available (and expensive) today.
