I caught this on one of the cable channels and was blown away by the cast lineup - Max von Sydow, Richard Boone, George Sanders, Dean Jagger, and - mirabile dictu - Orson Welles. What could go wrong, says I, in a Cold War intrigue drama with such a lineup, and directed by John Huston (who puts in a cameo)? As it turns out, plenty. I wondered why I had never heard of this flick, and after watching it, I realized why. The plot is incomprehensible, involving a mysterious letter that must be retrieved. It turns out that this letter, which we learn of at the beginning of the movie, is nothing more than what Hitchcock called a "McGuffin," an undefined object which gives the director an excuse to strut his stuff. In this case the "stuff" is a beautifully filmed exercise in obfuscation. It is never clear at any point who is doing what to whom. Huston got Welles to play a role, but he phones in his part in the pompous way of his later years. After a couple of hours of confusion, the ending, rather than giving us any closure (heaven forfend that a viewer might ask for closure), merely prolongs the incomprehensible. In sum, a confusing, overwrought, pretentious mess. The only upside is that it is beautifully shot. I wish I could also say that it's a pleasure to watch, but good cinematography only takes you so far. The frustration of the confusing plot kills everything. Skip it.
