Karen Idelson The subtleties of war. The struggle with loss and grief. The search for a home and belonging. The terror of puberty. The realization of mortality. This year’s Oscar nominees in the animated feature category never shied away from the big issues. Underneath the bold exteriors of their artistic and technological achievements, each one embraced difficult, rich themes. “I think there’s a way that young and old can both feel the emotion and the meaning of the story,” says “Puss in Boots: The Last Wish” helmer Joel Crawford. “Puss’ story is something we can all relate to in a way. He’s this fearless hero who has this moment where when he comes across the wall, feels fear for the first time because he knows he’s run out of lives and that he’s mortal — like all of us — for the first time. That moment is an impression of fear that I think everybody can feel. But then we are also able to tap into to some brighter kind of themes as well like hope through this impressionistic style we used in the animation.
