When Broadway.com asked Tony nominee Douglas Hodge to let us spy on his transformation process at La Cage aux Folles, we almost forgot a crucial fact: Most of it happens onstage, during Albin’s opening number, “A Little More Mascara.” Still, a surprising amount of prep work goes into turning Doug into Albin before he becomes the fabulous drag star Zaza. (Confused? See the show; you’ll love it.) Before a recent matinee, Hodge invited photographer Jenny Anderson into his powder-blue lair at the Longacre Theatre to see what happens before Jerry Herman’s overture bids the audience welcome…to La Cage aux Folles.
