MICHAEL CLAYTON

There's a spirit of fatalism and dread that hangs over nearly every scene in Tony Gilroy's legal thriller Michael Clayton, and the miracle of the movie is that its grimness doesn't equal torpor; for a work drenched in both literal and figurative darkness, it's exquisitely, robustly entertaining. Like the films in the Bourne franchise (all of which Gilroy scripted), Michael Clayton is a smart, knotty diversion that keeps your senses, at all times, alert, and happily, the movie's ecologically minded plotline - involving an agricultural chemical company being sued for poisoning communities - doesn't have sanctimonious intent. The movie isn't designed to be Good for Us; it's just designed to be good. And it's very, very good.

300

Whatever its problems, and they are myriad, you can't say that Zack Snyder's 300 doesn't give you plenty to look at. Adapted from Frank Miller's and Lynn Varley's graphic novel, the film - which follow s the ancient Spartan army in a wildly violent, self-sacrificing battle against Persian forces - is filled with memorably outré images: an enormous tree and a 20-foot-high wall, both composed entirely of corpses; a triad of elephants, backed over a cliff, that plunge to their deaths; the sky blackening with what appear to be locusts, instead proving to be the incoming trajectory of thousands of steel-tipped arrows. In 300, Snyder shows a remarkable gift for graphic-novel composition, and continually keeps your eye engaged. Too bad the same can't be said of your brain.

JARHEAD

In movies, nothing is harder to define than tone, and the tone of Sam Mendes' Jarhead, based on Tony Swofford's Gulf War memoir, is so elusive that, hours after it ends, you might still not know what to make of it. In many ways, the movie is like a two-hour expansion of Full Metal Jacket's first 40 minutes, as the 20-year-old Swofford (Jake Gyllenhaal) and his fellow Marine recruits, pumped up to an almost insane degree, train for their mission in the unbearable desert heat and prepare for battle. In Mendes' film, however, there is no battle for his protagonists to respond to; the war ends while the Marines' bloodlust is still reaching a boil. The film is, in many ways, about the maddening banality of service, and it has resulted in an occasionally maddening movie, but its shifting tones and air of unpredictability make it impossible to shake off; at the finale, you might not know exactly what you've seen, but you certainly know you've seen something.

WINGED M IGRATION

At the beginning of Jacques Perrin's documentary Winged Migration, even before the title has appeared, we are informed that the film took more than four years to complete, that it required near-global group participation, and that "no special-effects shots were employed in the making of this film." It seems like an overly grandiose introduction until you actually see the movie. For Winged Migration, currently playing at the Brew & View, is an absolutely astounding experience, a visually breathtaking work that is also more pure fun than just about anything in current release.
