The underlying idiocy here is to rip off the premise from "The Dirty Dozen ", which had had huge success just 2 years earlier, but to give the movie some half-baked bleedin'-obvious message about dirty war always being waged on both sides of any conflict. The trouble is, you just can't have it both ways. You can't have your cake and eat it too. You can't f*rt and keep it inside too. You either make a fairly unrealistic but fun semi-comedy about a bunch of criminals going on a suicide mission OR you use the movie to make some "grand" statement about the inherent ugliness of the decision-making process in the upper army tiers, i.e. some tired old morality tale.
For people who consider this movie to be "realistic", I have these five words: "Alice In Wonderland" and "Fantasia" i.e. you have seen them far too often. The LOOK of PD may be realistic; there is no denying the visual quality. The story, however, is anything but.
For example, Leach's baffling decision to sabotage Caine's attempt to bring the jeep over the hill. Leach – for whatever unexplained reason – decides to not unload the supplies off the vehicle as Caine had ordered, thereby allowing a perfectly good jeep to be destroyed, plus much of the supplies on it. What the hell was the point of that? Motives, anyone? I'd truly like to hear whatever theories, i.e. any fanciful (desperate) spins, which fans of PD can give me here to justify that dumb nonsensical act. Leach was portrayed as the ultimate survivalist, always looking out for himself first (and Caine second, due to the reward), so it made zero sense for him to diminish the chances of the mission succeeding, thereby also increasing the risks to his own life. This is moronic writing, and has absolutely nothing to do with the alleged "realities of war" that PD supposedly stands for. It was a childish act, perhaps, but that would totally out-of-synch with Leach's rather clear-cut character.
Worse yet, that entire sequence lasted for an eternity. Why does the viewer have to watch the boring details that are entailed in transporting a jeep over a hill? That seemed like the kind of padding that is usually found in cheesy 50s/60s B-movies and "arty" Euro-trash films with a thin or non-existent story. (Like those endless climbing sequences in "Lost Continent" or "The Mole People".) PD could have been cut by at least 15-20 minutes - that's how much it drags at times. It's as though the director was so keen on making the most of shooting on location, that he couldn't bring himself to slash some scenes that show the desert in all its cinematic glory. He basically sacrificed the movie's pace in favour of the scenery. But this is isn't supposed to be some slow, meditative flick about existentialism or any other such pretentious twaddle. It's a bloody war film.
Caine and Leach, who had been clever up to the point of blowing up the German supplies base, are suddenly reduced to utter retards when they walk straight into an ongoing military operation (Monty's invasion), waving a white flag that is smaller than a hamster's bum. Of course they could get killed by friendly fire! Even a person who knows nothing about the military, wars, or surrender would have figured that it's safer to wait out the invasion, to hide until the invading army is done with their invading, which would have taken no more than another hour (or hours at the most), and THEN "surrender". At the very least they could have taken off their German uniforms: it wasn't anyway as though they were going to freeze in Northern Africa, in the middle of the day, without these clothes. Dumb.
