The Diamond Wizard (1954; Brit., The Diamond) is a run of the mill crime drama, featuring the theft of new American coinage. Now in Britain, it is laundered through the device of financing the creation of synthetic diamonds using a new process devised by Dr. Miller; the plan is to sell the diamonds as natural for a whole lot more.
Dr. Miller is an innocent inventor, and thus he’s kidnapped and forced to work for the thieves. Miller’s daughter, Marline, happens to work for the police, so when she becomes alarmed, she discovers that her father is suspected of being a criminal himself. Between American Treasury agents who find her attractive and thieves who consider her ineffectual, she becomes a victim herself, held in the abandoned factory where the diamonds are being manufactured.
By large, dangerous machinery.
But such machinery … well, let’s not give the game away. The characters try hard to reach reality, but remain trapped in their 2-D world, and the more nuanced consequences of being a criminal are largely unexplored. There are clever bits, but here I am, a month out on writing a review, and not remembering the plot very well at all. I am thus led to conclude this was unmemorable.
But still a bit of fun.
As an addendum, Wikipedia tells me this movie was filmed in 3-D. This was a surprise to me, but if you have the facilities, it might be worth tracking down a 3-D print of the film.
