Edmund Hillary and Tenzing Norgay's 1953 ascent of Mount Everest is retold through a seamless combination of archive materials and modern-day re-enactment, making for what feels like an authoritative but slightly stiff history. Panoramic visuals are a given (the modern footage was shot in New Zealand), and the context and risk factors are well detailed, though the storytelling often feels closer to the 1950s than the present day. There's little curiosity about Hillary and Norgay's personalities, or their position as outsiders on a predominantly British expedition – effectively a colonial last hurrah. Still, it's a testament to the film-making that, despite the fact that we know the outcome, there's a great sense of relief when they finally reach the summit.
