"The Gilded Cage" is an invaluable portrait of some legendary lady supposed to have been painted by Degas, while he of course never painted such a portrait. The thriller intrigue is spun around this portrait, which some rogues plan to steal from its well established gallery, but of course such a theft could never be accomplished without help from the inside. Some ladies are involved, and the American Harry is involved with one of the ladies, who tries to warn him to stay out of the racket. His brother (Alex Nicol, a bit like Dennis O'Keefe) arrives from the states to find his brother vanished. When he tries to get a clue of how to find him from the actress his girl-friend, she gets murdered, and so the mess keeps developing with more murderous attempts, kidnappings, fisticuffs and all kinds of intrigues and atrocities, until the brother finally gets shot, and then you don't hear of him again, although he is said to still be living. It's an ordinary thriller with interesting London settings trying to muddle up the intrigue to puzzle the audience, and finally things get sorted out. The most interesting actors are Ursula Howells and Elwyn Brook-Jones, who both get murdered, and Clifford Evans, but the best thing in the film is the music by Stanley Black. The smiling man Ronan O'Casey adds some creepy spice to the intrigues but isn't the most dangerous man in the plot.
