Keisha Castle-Hughes in Whale RiderWHALE RIDER

Among its many, many virtues, what I loved most about Niki Caro's Whale Rider is its toughness. In the past year, we've seen so many variants on the ethnic-female-overcoming-her-family's-prejudices theme - My Big Fat Greek Wedding, Real Women Have Curves, Bend It Like Beckham - that the idea of sitting through another one, even one set on a staggeringly gorgeous New Zealand seaside, filled me with more ennui than expectation.

Kevin Costner and Robert Duvall in Open RangeOPEN RANGE

What will it take for Kevin Costner to give a performance again? His new movie, the western Open Range, which he also directed, has a lot going for it - beautiful camerawork, impressive editing, a strong, simple storyline, a marvelously cantankerous Robert Duvall - yet smack at the center is sweet, dear, painfully inadequate Kevin Costner, looking and sounding so uninvolved with his surroundings and his fellow actors that he weakens his entire film. (It took great restraint to laugh at him only once, at his hysterically unmotivated reading of the cowpoke classic "Let's rustle up some grub.") Some will argue that Costner is actually deeply in character, playing an uncivilized man for whom conversation and companionship offer little comfort, but look at him onscreen: His Zen blankness is indistinguishable from a coma, and his "concentration" resembles nothing so much as a somnambulist struggling to stay awake. As usual, Costner is fine with rare moments of fringe comedy - reminding us why we once liked him in movies like Bull Durham and Field of Dreams and Tin Cup - but he's positively deadly in Open Range, and not because of his character's prowess with a gun.

Ben Affleck, Morgan Freeman, and Lev Prygounov in The Sum of All FearsTHE SUM OF ALL FEARS

In The Sum of All Fears, the latest film adaptation of one of Tom Clancy's Jack Ryan thrillers - the other movies being The Hunt for Red October, Patriot Games, and Clear & Present Danger - America and Russia are headed for war. In a horrifying scene that, given our national consciousness, might deeply unsettle audiences, a nuclear device has detonated at a football stadium in Baltimore, and all indicators point to the Russians and their new president (Ciaran Hinds) masterminding the attack. Our government, and our mildly befuddled president (James Cromwell), are readying a counter-assault that will inevitably lead to World War III, but Jack Ryan, our one-man CIA, knows that something's just not right about our leaders' assumptions, and tries to ... hey, wait a minute, is that Ben Affleck playing Ryan?
