Who the #$&% Is Jackson Pollock? is a 2006 documentary following Teri Horton, a 73-year-old former long-haul truck driver from California, who purchased a painting from a thrift shop for $5, only to find out later that it may be a Jackson Pollock painting. She had no clue at the time who Jackson Pollock was, hence the name of the film.

Paul Jackson Pollock was an American painter. A major figure in the abstract expressionist movement, Pollock was widely noticed for his "drip technique" of pouring or splashing liquid household paint onto a horizontal surface, enabling him to view and paint his canvases from all angles. It was called all-over painting and action painting, since he covered the entire canvas and used the force of his whole body to paint, often in a frenetic dancing style. This extreme form of abstraction divided the critics: some praised the immediacy of the creation, while others derided the random effects.
