Only Katie McFadzen could pull off playing bitchy Mrs. Cratchit, sickly-sweet Tiny Tim, and that blowhard Ghost of Christmas Present, while also making something of Charles Dickens' 173-year-old narration in a one-woman production of A Christmas Carol. McFadzen adapted the script herself, from the original text, with the help of director Matthew Wiener. It played last winter at Tempe Center for the Arts, and was way more than a recitation, even while it quoted great hunks of the Dickens novella. Rather than inhabit each character, McFadzen described them with distinct voices and slightly altered stature — a subtle trick that elevated this 80-minute adaptation, turning a how-did-she-do-that curiosity into a tidy entertainment.
