At 88 years old, Audrey Flack — feminist, rebel, mother, painter, sculptor, and teacher — holds a unique place in the history of contemporary art in America. Flack’s often-controversial 40-year career evolved from abstract expressionism in the 1950s to photorealism in the 1970s to monumental sculpture in the 1990s. One of the first women ever included in the famed “Janson’s History of Art,” Flack continues to create, explore, and inspire with her unique style and indomitable spirit, and “Queen of Hearts” follows the artist as she takes her work in yet another new direction. Although the focus remains on her work, the film also explores Flack’s personal life, especially the difficulty of balancing her career and her family, which included a severely autistic daughter (at a time when autism was not well understood and support was hard to come by). Her career also coincided with the rise of feminism, and the doc explores the specific challenges of women in the art world. “Queen of Hearts” is a moving portrait of an artist who is still testing, still experimenting, still searching. The film is co-directed by former St. Louisan Rachel Reichman — a SLIFF alum for her own film “Work” and as editor of “Hitchcock/Truffaut” — and executive-produced by local philanthropist Mary Strauss. Hammer to Nail writes: “A thoroughly engaging documentary portrait, ‘Queen of Hearts: Audrey Flack’ is the perfect introduction to its subject, comprehensive in its detail and captivating in its approach.”
