Who the #$&% is Jackson Pollock?

After Teri Horton—a gruff, foul-talking, dipsy-dumpster-diving 73-year-old former truck driver—bought a painting for five bucks from a thrift shop, a local art teacher told her that the work might be a Jackson Pollock, prompting the titular question—Who the #$&% is Jackson Pollock?—and propelling Horton into a decade-plus battle with the art world. Filmmaker Harry Moses' engaging documentary combines dramatic reenactments, comments from art experts (most notably the condescending Thomas Hoving, former Metropolitan Museum of Art director), a CSI-type art detective named Paul Biro (who matches a fingerprint on the back of the canvas with a print from Pollock's studio), and Tod Volpe, a onetime art dealer to Hollywood stars (including Jack Nicholson), who went to prison for fraud and is hired by Horton to represent the sale of her “Pollock” (Horton saw Volpe's book Framed in a bookstore, and though she'd “never paid $25 for a hardcover book in my life,” she picked it up and enlisted Volpe's aid in reaching the insular art world). Throughout, one of the primary issues at stake is the lack of “provenance” (i.e., the painting's history—critical to verifying authenticity), which makes dealers reluctant to even consider looking at any painting unaccompanied by an extensive paper trail, regardless of forensic evidence. An offbeat profile of one woman's determined fight to be taken seriously, this is recommended. Aud: C, P. (R. Pitman)
