A weirdly dull Cold War parable that has a few good moments of comedy, a completely unnecessary romantic subplot, and an unfortunate Peter Sellers-in-drag joke that doesn't do anything for the film. Its premise is a fun one, but the film is mostly concerned with admittedly fun slapstick and doesn't draw enough from the setting of Grand Fenwick to make that aspect of it matter save for a cloying ending--one whose sentiment I can kinda get behind, but the execution is just a bit weak.
Had they the nerve to end with the faked ending, I would have been utterly delighted. The use of the particular imagery of the fake ending was also surprising and potent. Til that point, the film had felt a little blunted, but that gave it a sharp edge at least for a moment.
My only other comment on this film is that Jean Seberg was something special.
