George Sanders has often been quoted as calling the Saint and Falcon films the "nadir" of his career. Looking at "The Saint's Double Trouble" it is easy to see why he felt that way (badly scripted, poor supporting cast, etc, etc) but his four other Saint entries, at least, are well up to scratch. If this one is a little slack in the chase and gun play departments, never mind. It is an old-fashioned "whodunnit" and Sanders and Paul Guilfoyle (as Pearly Gates, a series regular) seem to enjoy themselves in this tale of missing stamps (worth a fortune) and suspicious characters at a luxury Palm Springs hotel. The plot may bear absolutely no resemblance to Leslie Charteris's short story, but never mind; it is a pleasant little cocktail with which to waste an hour or so. By the way, you're guaranteed not to guess whodunnit, although the chief suspects are shown quite often. No one except Sanders would think of this amiable film as a career low-point; it's a pity he didn't make a few more like this as his career went on.
