He attacked gun culture in Bowling For Columbine, George W. Bush’s Iraq War in Fahrenheit 9/11 and the American health-care system in Sicko , but now Michael Moore is set to take on capitalism itself in his as-yet untitled next film – which is due out in the US on October 2 and hopefully here soon after.

The film sounds like a return to his Roger and Me filmmaking roots, as that 1989 film had him attempting to tackle the head of General Motors for closing down the plant in Moore’s hometown of Flint, Michigan, leaving the town in an economic mess. This time, however, the target’s global capitalism itself, with Moore planning a comic look at the corporate and political shenanigans that culminated in what he describes as “the biggest robbery in the history of this country” – the massive transfer of U.S. taxpayer money to private financial institutions.

The film will come out a year and a day after the US Congress voted for the Wall Street bailout, and comes two years after Moore’s last effort, Sicko. So are we still excited by a new Moore documentary? This one’s shooting fish in a barrel – isn’t it?
