In the 1800s, after an assassination attempt by Prince Ramon against the king of Mandorra, a brigand resembling the king surreptitiously impersonates the incapacitated monarch in order to throw off the plotters.
Anthony Dexter does a double role, one as a Sultan guard called Carlos who brandishes a fair sword and other a frivolous king Lorenzo who loves dancing with ladies and has this annoying tendency of doing a "ha ha" laugh every few seconds. He fairs well in these roles, making a good contrast between the two, and he's got a certain style and charisma, and he's good at the action bits. Anthony Quinn plays the royal cousin of King Lorenzo who plans a "premeditated accident" to King Lorenzo by giving him a hunting weapon that is rigged to fire backwards so he can push himself on the throne and marry the princess, and he's at his usually slippery self as the villain. Jody Lawrence is ok as the princess but someone more striking and more expressive would've been good.
The Brigand has an uncanny resemblance to the Prisoner of Zenda, and though it's not as striking or as exciting as that film ( the Ronald Colman and Stewart Granger versions), it's a competently made and an adequate viewing with lavishness, colour, some style, set pieces and some good swordplay. Phil Karlson keeps everything zipping along. Unlike the Prisoner of Zenda, it has a more happier ending for Dexter's Sultan guard in regards to the princess.
