The movie was decent but his masterpieces were the tv interviews, where he would pretend to be "the voice of yoof" and totally ridicule people who thought they were important (and some actually important as well). Fo real.
If you thought the interviews were funny, check out a series called Brass Eye. Its a fake tv news show, with a really really dark & sarcastic sense of humour. The shows are a couple of years old, and a bit dated, but they are such an accurate pastiche of tv news culture that it hurts. and very very funny
