Ban This Filth (2004)

Spoof documentary following a trio of pensioners who embark on a moral crusade against the rise of sexually explicit material on TV, film and the Internet. However, their unusual tactics consist of acquiring as much graphic imagery as possible and publicly displaying it, in an attempt to warn people what is out there.
