Who the #$&% Is Jackson Pollock?

Teri Horton, a salty, truck-driving grandmother, buys an abstract painting in a thrift shop for $5. A local art teacher suggests it might be a Jackson Pollock worth millions. Grandma takes on the snobbish and skeptical art world, enlisting a forensics expert and a renegade dealer in her dogged 15-year quest to prove she owns a masterpiece. This documentary, executive-produced by 60 Minutes’ Don Hewitt, boasts a populist, Frank Capra--esque spirit (call it Ms. Horton Goes to MoMA) but is more comfortable eliciting easy chuckles than asking, what is great art?
