A true story about a hard-scrabble twice-divorced unemployed mother-of-three who became a legal assistant and wound up helping win a class action suit to the tune of a third of a billion dollars for the citizens of Hinkley CA who were being poisoned by the water in their area. This is anything but a Sickness of the Week movie. The sharp as a tack screenplay by Susannah Grant is beautifully structured, with snappy dialogue to die for – when biker Aaron Eckhart asks Erin what would he have to do to be different to her former husbands, she says, Stay – this is anchored by good aesthetic decisions and a great performance by Julia Roberts who gives it her all. Albert Finney is her long-suffering lawyer boss (she persuades him to hire her after he loses her traffic accident suit) and this is never less than totally believable in a marvellously judged production about going up against corrupt corporations, directed (and photographed) by Steven Soderbergh. That’s the real Erin B ten minutes in, taking Julia’s orders at a restaurant.
