The cameraless animated short they rise, these sponge fortresses is made from a 35 mm trailer of the feature film Water Lilies (2007) by Céline Sciamma. Experimental filmmaker Guillaume Vallée explores and questions his sensory memory as a teenager, partially lost. This process of resuscitating buried experiences and forgotten memories is carried by the materiality of 35mm film, the nature of the images filmed and the interventions of the filmmaker painting and scratching the film emulsion directly. In this reverse journey, the memory-images, the affects reveal their plasticity, their imperfections, their chaos, their sensuality and their significance. The soundtrack is by Stephanie Castonguay and the texts by author Gabrielle Boulianne-Tremblay.
