For the scene where Rolandsen has deserted to live on the uninhabited island, trained sea lions from a company in Switzerland were freighted in water tanks to the location in Northern Norway. On the day of shooting, the sea lions didn't want to come out from their water tanks to do their part. The entire crew and actor were on stand by, waiting for the sea lions to become familiar to the environment so they could shoot the scene. The sea lions never came out and they had to send them back home to Switzerland. A couple of weeks later, trained sea lions from a company in Belgium were sent to the same location to do the scene, hopefully with a better result. The sea lions trained in Belgium didn't have stage fright so the scene could be successfully done.
