When it was released in 1950, "Halls of Montezuma" was one of the most realistic and ambitious war movies yet made. Today its strengths still outweigh its unfortunate flaws. The flaws are an all-too-familiar sentimental streak, an absurd "revelation" about Japanese tactics, an unconvincing psycho in a clumsy explanatory flashback, and the unlikely presence, in Lt. Anderson's platoon, of a replacement who just happened to have been one of his high-school students in civilian life.

Many viewers will find such flaws even more annoying because they detract from the good things about this movie, including some solid performances (Widmark, Palance, Boone, Webb) a realistic plot, an unusually authentic look--including some (mostly) well integrated combat footage--and a spectacular scope. Until "The Longest Day" (1961), the beach landing here(with flame-throwing tanks)and the later assault on the Japanese were more impressive than any other screen depictions of a large military operation. (BTW, the failure of the Japanese to oppose the landing itself isn't a Hollywood howler; the movie accurately reflects the Japanese defense strategy on Okinawa in 1945.) Milestone's directorial masterpiece, "All Quiet on the Western Front" (1930), expresses revulsion at the slaughter of World War I. "Halls of Montezuma" affords a more complex view of men in World War II. The hero is a high-school chemistry teacher whose migraines have addicted him to painkillers; he doesn't care because he assumes he's going to be killed. One character is blinded and another killed by accident. By modern standards such incidents may seem relatively mild, but during the war such troubling images were thought to be too disturbing for film-goers. Even in 1950 they were strong stuff for a movie.

Made at a time when the Cold War was heating up dangerously in Korea, "Halls of Montezuma" is still a revealing postwar response to World War II in the Pacific.
