GoldDerby has posted some surprising details for the 2014 awards season. Two years after winning Best Actress for “The Iron Lady,” Streep has agreed to drop down to the supporting race for her role as Violet, the pill-popping, booze-swilling momma in “August: Osage County,” a Weinstein Company source tells Gold Derby. That means Streep will compete against Oprah as the hooch-guzzling wife of the title star of “The Butler,” which is also a Weinstein flick. Hmmm … what is Harvey thinking? Streep’s move is a shockeroo considering that role won Best Actress at the 2008 Tony Awards when Deanna Dunagan performed it on Broadway. Dunagan beat her costar Amy Morton, who portrayed Violet’s frazzled daughter Barbara. Now Julia Roberts, in the role of Barbara on screen, seems to have a clearer shot at a Best Actress victory without risking a split of “August” votes in that category. Streep’s gracious move may be good news for Roberts, but it’s rotten luck for “August” costar Margo Martindale, who portrays the role of Violet’s sister Mattie, which won the Tony Award for Best Featured (or Supporting) Actress for Rondi Reed on stage. Now past Emmy champ Martindale (“Justified”) must not only face off against Oprah, but Streep, too. Let’s see if they don’t change their mind once award season comes closer. Thanks to Glenn for the heads-up.
