And this is why Elvis is the King. Not because he made dozens of these movies, most of them total cheese. Not because they’re all full of corny scenes where he can just stroll into the local gym and get begged to do a song like this. ("C’mon Everybody" is no relation to the Eddie Cochran rockabilly classic of the same name, except they're both awesome.) No, he's the King because of the superhuman confidence he brings to every moment. That's also why he brings the seductively leotarded Ann-Margret to an orgasmic frenzy with just the quiver in his voice. He makes her Sweden-sired hips undulate right next to his, for the ultimate cinematic hip-shake battle royale. And what a battle it is – though Elvis would be the first to admit that even the King can't outwiggle Ann-Margret.
