Last night’s August: Osage County cast discussion included an interesting comment from playwright/screenwriter Tracy Letts about Meryl Streep‘s Violet Weston character, an abrasive, drug-addled matriarch who is based on his real-life maternal grandmother. Since the 2007 stage debut of Letts’ Pulitzer Prize-winning drama, Violet has been routinely referred to as one of the most caustic and abrasive female characters ever depicted, but Letts said last night that she’s actually a toned-down version of the Real McCoy. When he first showed August: Osage County to his novelist mom Billie Letts, she told Letts that “you’ve been very kind to my mother.”
