Jandy Hardesty’s review published on Letterboxd:
This is far more a Bing Crosby film than a Billy Wilder one, with Bing as an American salesman dead set on selling Austria's Emperor Franz Joseph on the phonograph and making a killing in Austria. Instead, his dog falls in love with a Countess's dog, and the he falls in love with the Countess. Yes, the dogs are important enough to the story to get first billing.
It's a slight affair, but it is interesting to see Wilder play his native country against his adopted one, and let me just say, Austria does not even come close to winning. The old-fashioned Viennese aristocracy are the butt of most of the jokes (they psychoanalyze a poodle at one point, for reals), while their distaste for Crosby's go-getter attitude is basically self-parody.
It's also one of the few color films Wilder did, and he uses the location shooting (the mountains of Alberta, Canada standing in for the Alps) for all it's worth. For a bit of fluffy fun, I enjoyed the film more than I expected.
