One of the most iconic scenes of the film Mission Impossible - Fallout is the fight between Tom Cruise and Henry Cavill on an imposing cliff edge. It was filmed at the Preikestolen (the Pulpit), a large rock outcrop in the mountains above Lysefjorden in Forsand, Norway… so where better for the film’s Norwegian première to take place? The event was hosted by Forsand Kommune, but a major problem was how to deliver high quality cinema sound to 2000 people on a mountain, 600 metres above sea level?
