If you’d asked me ten years ago which viral short film do you least expect to get a feature-length adaptation, I would have said SALAD FINGERS (2004) followed by MARCEL THE SHELL WITH SHOES ON (2010). The eventual feature film turns out to be a marvel of technically complex stop-motion animation which also captures something poignant about loss, trauma, dementia, and ageing. There’s a surprising amount of the writers in the film: the line about discovering that an audience is not the same thing as a community feels profoundly true.
