I haven't seen the whole movie, but just happened upon the last 15 or 20 minutes on TCM. Most of this time was filled by a chase scene that was actually kind of exciting (though it strained credulity that Our Hero wasn't killed about 8 times) and often funny. I was often thinking, "How did they do that?" I don't know about the rest of the film, but his part was definitely worth seeing.
An interesting aspect of changing technology was that the object of the chase was to get/keep possession of a phonograph record, presumably the only copy of an important recorded conversation. It wouldn't have happened in the digital age!
