World events and current affairs invariably inspire cultural commentary, in terms of both entertainment and factual responses, and it is no exaggeration to speculate that if an event, or an idea is worthy of note for documentary filmmakers and straight literary commentators, it will inevitably already have been considered by someone in Hollywood as a potential money-spinner. Just look at how quickly the Kill Bin Laden project was confirmed after the death of arguably the most wanted man in Western history. Recent years have seen the blurring of the distinction between serious exposes and their Hollywood counterparts, as filmmakers like Michael Moore and Morgan Spurlock have used more commercial arenas to promote their messages, and we can now talk about documentaries in terms of their box office appeal and potential bankability. Add to that the fact that revolution is hot right now, with notable uprisings taking up slots in the news almost every day, and you could suggest that this is the perfect time to be making and releasing anything that successfully blends a compelling story with a spirit of dissent. Into this context, filmmaking spouses and activists Joshua Tickell and Rebecca Harrell have made The Big Fix (sometimes known as Spill), a documentary charting the continued after-effects and alleged cover-up of the Deepwater Horizons oil spill in the Gulf of Mexico, which screened this afternoon as a Special Screening in Cannes.
