The peace-catchers are the boys and girls of Class Three H of the Farini Middle School in Bologna who - under the direction of the ingenious technical education teacher Marianna Babina - experimented with all possible animation techniques in order to launch a pacifist message to the world. The film, of which we show an extensive excerpt, is exemplary of the short-form cinema produced at school over a fifteen-year period, starting in 1975, thanks to the initiative of a teacher full of passion and inventiveness. 'Peace Catcher', which will participate in children's film festivals and reviews, opens on a peace event and then follows the entire creative process from conception to realisation. It starts in March, in the first days of spring 1986. And here we see in succession the results of the workshop led by Babina: the short animations of these schoolchildren and the power of the pacifist imagination in power. At the end, the children who made the film present themselves one by one, giving us an extraordinary moment of cinema truth (in the classroom) catched by Marianna Babina.
