In my blog post about director Jerzy Skolimowski last Friday, I failed to mention that one of his best films, 2010’s Essential Killing, was recently released on DVD in the US. This is good news. Given its emphasis on snow and isolation, Essential is a perfect movie for winter—it’s also an ideal companion piece to Joe Carnahan’s The Grey, which opens this weekend. Both films are tales of survival set among snowy landscapes that grow into moody meditations on death: in an ideal movie culture, theaters would be showing them back-to-back.
