This Friday, Non-Stop hits theaters, and moviegoers worldwide will be treated to one of cinema’s greatest treasures: Liam Neeson’s murder-face. For decades (and especially since 2008’s Taken, when he made abruptly growly voiced executions his main thing), Neeson’s sneer has been the last thing his characters’ foes have seen before hurtling off into bad-guy heaven. But Neeson (or “Neesons,” if you’re a true fan) isn’t a one-note actor. His murder-faces are nuanced and varied, and we’ve analyzed a potpourri of them. We’ve assigned a “sneer quotient” for each on a scale of one to ten, with one being “he’s gentle and regretful” and ten being “you tried to kill his daughter.” Look at our annotated slideshow now. If you don’t, we will look for you, we will find you, and we will kill you.
