Before Hindsight.

Newsreels from the '30s constitute the bulk of this fascinating documentary, clearly illustrating that the public was fed an extremely biased view of events: straight propaganda, the stricture to provide entertainment, and the attempt to be objective all contributing to this. Lewis and producer Elizabeth Taylor-Mead have constructed their argument well, but it is Jonathan Dimbleby's brief comments towards the end that contain the crucial lesson: forty years on, the same forces work to distort our view of Northern Ireland. The film only indicates this to be the case, but it is precise and coherent enough to make the point with considerable force.
