Not so cool breeze in the enchanted forest

 A PIG ON a trampoline goes flying toward the screen, his sizable rear end smashing against the glass. A sloth doing yoga ties himself up in knots, leaving his face, as he laments, perilously close to his butt. A cute bunny unexpectedly poops and shakes his tail at the camera.

Moviegoers tuned into this summer’s film slate are well familiar with these animals’ backsides, which arise triumphantly at the ends of ads for the animated films “Angry Birds,” “Ice Age: Collision Course,” and “Secret Life of Pets,” respectively. What’s going on here is rather subtle. OK, not the jokes. And not the alignment between form and content evident in so many tails appearing at the tail end of ads. No, what’s subtle is the message all these butt jokes communicate: These movies are for boys.
