Title: The Wave (2015 film)
Passage: Norway is a rockslide prone area (created by the Caledonian orogeny) and The Wave is based on a rock-slide tsunami incident which destroyed the village of Tafjord on 7 April 1934, killing 40 people. Prior to that, a similar incident in 1905 triggered a tsunami killing 60 people, and 31 years later, another 74 lost their lives. Uthaug has always been a fan of Hollywood disaster films such as Twister and Armageddon and had long wanted to make a disaster film in Norway. According to him the challenge was to combine the elements of the American genre film with the reality of the situation in Norway.
