I saw this movie long ago and thought it was pretty amusing. Woody Allen took a Japanese spy movie, recut it, and dubbed it with U. S. actors doing mostly one-liners that had nothing to do with the original plot. So, for example, whatever the MacGuffin was in the original movie has become the recipe for the world's best egg salad. The trailer and the poster give the impression that Allen is in the movie. He is, but only in the prologue at the beginning, when he tells about making the movie.Little did I know that the movie I saw wasn't the one that Allen intended for me to see. It had been altered with dialogue being added, along with additional scenes from another movie. And the Lovin' Spoonful. Yes, the Lovin' Spoonful sings a couple of numbers during the course of the movie for reasons that are obscure other than that somebody wanted them in there.
Or that's one version of the story, at least. There are others. I don't think anybody really knows for sure how many versions of the movie there are or which ones exist on current DVDs. It's something worth a look, though, if you want a movie unlike just about any other. The one-liners are hit and miss, but they hit more often than they miss. Or that was my long-ago impression. Now they might all fall flat.
