In the 1970 Doctor Who serial 'Inferno,' one parallel world on the brink of calamity due to a drilling incident gone terribly wrong serves as a warning for the other earth. Of course, reality does not work like that, even on a much smaller scale, like say that of countries. But in the case of Ghana and Nigeria, maybe for once it does, while it should be pointed out that of course all African countries are not the same. In 2007, Kosmos Energy took a huge risk and discovered oil off the shore of Ghana. As negotiations and elections follow, eyes turn toward Nigeria as an object lesson in what a country should not do with its share of the oil money, as Nigeria became rife with corruption, thus leaving many whose lives should have been improved by government development, instead forced to make a risky living on the oil black market to eke out a subsistence living.(The Norwegian suggestion concerning taxation is by the most fair for everybody involved.) That also causes some to turn to militancy in sabotaging the pipelines to get their point across. In the very incisive documentary and cinematic essay "Big Men," Rachel Boynton not only talks to those same insurgents to get a sense of what they want(and also some keen interpretation on what a documentary means), but also to those sitting in the boardrooms in New York, like James Musselman, the front man for Kosmos. And then she talks to everybody in between to get as many points of view as possible while also showing the high stakes involved for all parties, even those not directly affected.
