A few days ago, rehearsals began in New York for Red-Hot Patriot: The Kick-Ass Wit of Molly Ivins, starring Kathleen Turner (right) as the late Texas columnist-wit. The one-woman play, written by journalists and twin sisters Margaret and Allison Engel, opens March 19 at the Philadelphia Theatre Company — and is widely seen as a Broadway tryout. In fact, the show is directed by Broadway vet David Esbjornson (Edward Albee’s The Goat), while Dallas’ own Tony Award-winner John Arnone (The Who’s Tommy) is designing the set.
