Even lavish sets and costumes and a background score by Miklos Rozsa can't save THE KING'S THIEF from the boredom of a banal script. Lots of flashing swordplay takes place, but none of it has enough sizzle to make up for a tiresome story about a scoundrel (David Niven) who is keeping his thievery a secret from Charles II (George Sanders).
The best sequence involves an adventurous escape from heavy chains in a prison dungeon and a final encounter in a tower holding fabulous jewels whereby our hero ultimately wins the approval of Charles II.
David Niven does well enough as the charming thief, handsome Edmund Purdom is nimble and rugged enough as a swashbuckling highwayman, and Ann Blyth is pretty in her costume finery. But none of them have more than cardboard characters to work with and the end result is a routine period adventure wasting a talented cast.
Even Rosza's score is less memorable than most of his work for this kind of swashbuckler.
