Revealing mistake: When Floki and fellow Vikings march across Iceland, an aerial view of Dettifoss waterfall is shown, including the visible tourist paths, fencing and a small stone bridge on the left, used by tourists to visit around the site. (00:31:15)

Factual error: When Floki lands in Iceland with the other Vikings brought from Kattegat, they land on the beach near Dyrhólaey, the southernmost tip of Iceland. Moments later, they are shown walking near the waterfall of Dettifoss, on the opposing side of Iceland. That is almost 300km (186mi) away, assuming they walked on a straight line across mountains, glaciers, valleys and a highly inhospitable desert in interior Iceland. If they went along the coast, that's more like 625km (390mi). (00:30:55 - 00:31:16)
