pretty typical except for the ending
8 February 2014 | by (United States) – See all my reviews

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.
