There are independent filmmakers and then there’s writer-director John Sayles, whose Twitter avatar and biography (“Original Independent”) could scarcely say it better. For more than three decades, he’s used his often lucrative work as a for-hire script doctor to help fund autonomous screen visions that explore a wide range of themes, from race, class and crime to political corruption and labor union turmoil. Go For Sisters is his latest film, his 18th behind the camera, and it stars Lisa Gay Hamilton as a no-nonsense Los Angeles parole officer who leans on the connections of a wayward high school friend (Yolanda Ross) when her adult son goes missing, tripping headlong into a twisted web of human trafficking and other criminal enterprises. I recently had a chance to speak to the warm and candid Sayles one-on-one and in person, about his movie, his career and why he’s not as likely to write things as ambitious as he once did. The conversation is excerpted over at ShockYa, so click here for the read.
