As endearing and energetic as Up may be, it would be fair to say that its most memorable scene is an early four-minute montage in which childhood sweethearts Carl and Ellie Fredricksen are shown starting their new life together. There's no dialogue, just perfectly realised snapshots of a marriage through the decades. By turns heart-warming and heartbreaking, we see them transform a ramshackle hut into the perfect home - but dipping into the savings jar to pay for a damaged roof only pushes that dream trip to Paradise Falls a little farther out of reach. The most poignant moment, in which we see the couple painting a nursery before the scene slides to them sobbing in the cold grey of a doctor's surgery, is guaranteed to bring a tear to your eye. There's so much hope, humour and humanity condensed into those four minutes that the following feature film feels more like an afterthought.
