Every day, a father and his son jump down a cliff from their cold cottage at the top of a mountain using a parachute to sell ice clogs they produce themselves in the village at the foot of the mountain. Portuguese filmmaker João Gonzalez uses that set-up to tell a story of loss and trauma while also subtly addressing climate change.

The beautifully animated Ice Merchants travelled the world and now has a chance to win an Academy Award. The film already feels like a modern classic and is reminiscent of Michael Dudok de Wit's successful Father and Daughter (which effectively won an Oscar at the time) in terms of its set-up and impact.
