Harrison Ford and Asa Butterfield in Ender's GameENDER'S GAME

In writer/director Gavin Hood's sci-fi adventure Ender's Game, our titular hero (Asa Butterfield) is a 12-year-old who's bullied both at school and at home, whose gestating anger leads to frequent violent outbursts, and whose frighteningly focused skills at computer-simulated war games not only earn him the respect of his peers but, eventually, the grateful thanks of every man, woman, and child on the planet. It is, in short, a Revenge of the Nerd fable to out-Carrie Carrie, and about the strongest argument for 24/7 video-game compulsion that any young game-hound could wish for. Just keep playing, you can hear the movie whispering to its console-obsessed demographic. One of these days, you'll show 'em. You'll show 'em all.

Liam Neeson in The GreyTHE GREY

Whenever I watch a movie such as Alive or The Thing or director Joe Carnahan's The Grey - especially in January - I ask myself the same question: Is it worth it? I know about cinematic sleight-of-hand, of course, and that the performers and crew aren't enduring anywhere near the nightmarish conditions suffered by the characters on-screen. I also presume that a fat Hollywood paycheck instantly makes any location shooting, including The Grey's outdoor shoot in wintry British Columbia, a lot more bearable. But still, all that ice and wind and trudging through thigh-deep snow ... . Is any movie experience worth spending three months in fear of losing your digits to frostbite?
