Controversial, confrontational and riveting, this unique work received worldwide critical acclaim for its filmic power, questioning how and why modern societies exploit animals for food, fur, sport, entertainment and science. It showed scenes that had never been filmed before and footage uncovered through dogged research. In the UK it was broadcast on Channel 4 during its first week on air in November 1982 and caused uproar and thereafter was shown in cinemas and on TV around the world.

The film is noteworthy for its groundbreaking ironic style, integrating diverse 'found footage' including cartoons, newsreels, advertisements, and government propaganda films, mingled with vox pops and rock music. The BFI DVD includes the volatile material which was censored on Channel 4 – filmed sequences of animal liberation raids and clandestine interviews with the campaigners involved.

Narrated by Julie Christie, with music by David Byrne/Talking Heads and a compelling score composed and performed by Robert Wyatt, the film inspired a generation of vegetarians, and remains an acutely resonant work for today.

For the record, the above description is straight from the press release, as such things often are, but I'll add a personal note here and tell you that I watched that screening in Channel 4's opening week with my younger sister. It left both of us shocked and my sister in tears. I have no doubt it was a factor in her decision to become a vegetarian and pursue a successful career as a veterinary nurse. Yes, it really is that powerful.
