Wal-Mart documentary may prove expensive

In Wal-Mart, High Cost of Low Price (Tartan, €24.99), Robert Greenwald turns his sights on the giant supermarket corporation.

Through a mixture of interviews with employees and campaigners, he examines the ethics of Wal-Mart exploiting its monopoly position to squeeze everyone from workers upwards.

Greenwald, whose Outfoxed memorably challenged Murdoch’s biased Fox network, delivers a fascinating insight into the world of multinationals.
