Continuity mistake: When Dani is looking at Simon and Connie complaining to Ingemar after the female elder jumps off the cliff and they turn back to face towards it, Christian says "Oh my God" realising the male elder is about to jump off. At this moment, he has his left hand over his mouth and his right hand by his side. The shot then cuts and Christian now has his right hand over his mouth and his left hand on his chest. (01:10:55)
