Back in the early eighties I used to go to a children's film club on a Saturday morning, which was basically a colour TV and VCR in a local hall, and half of my school sitting on the floor watching whatever they rented for us.
One week they obviously got the wrong tape in the box, because instead of the film they intended to get we ended up watching something about a window-cleaner on a sky-scraper.
Children were bored and starting to complain, there was a bit of language which probably should have warned the adults supervising. And then the window-cleaner somehow got beheaded and his neck stump was shown in gory detail against the window he'd been cleaning and the whole place was in uproar, kids screaming and crying all over the place.
Someone was swiftly dispatched to the video shop to complain and get a proper film, and they came back with this "nice cartoon about rabbits."
Well by the end of it we'd have been better off sticking with the decapitated window cleaner film.
Kids had nightmares, kids were crying, one girl said she didn't want to keep her pet rabbit anymore because she was scared of it, hardly anybody was brought back the next week because of the upset.
I've never watched it again, and this afternoon I made sure DS didn't get anywhere near the channel it was on.
My mum said I'd like it better if I read the book, and she gave me a copy of that and the one about the plague dogs. I took one look at that little black and white dog on the cover with the bandage on his head and thought fuck it, I'll never get over it if I even try to start it. Sent them both to the charity shop unread for some other poor sod to cry over.
