Factual error: After Red receives the package containing the tooth, it cuts to a city image that reads "Warsaw, Poland" but the city shown in this image is not Warsaw, it is actually Budapest, the capital of Hungary. This specific image shows the Széchenyi Chain Bridge (Széchenyi Lánchíd) and the Buda Castle (Budavári Palota), in Budapest. (00:06:50)
Factual error: In the scene, Floki walks towards a small waterfall today known as Kvernufoss. Floki is supposed to be the only inhabitant if not the entire Iceland, at least the region, as we are shown no sign of civilisation whatsoever, and as historical record tell us about Iceland in the early 800s (as the events of Vikings seem to take place). But a well beaten footpath is visible, leading to the waterfall at the end of the canyon. That path is an oft-travelled path tourists follow nowadays to reach Kvernufoss, a well-known site in the area. A path like that in Floki's time would simply not have existed (there is nothing in that canyon but that waterfall, no reason to go there if not for sightseeing) and represents a (tiny) intrusion of our modern world in a show set in the middle age Iceland.

Continuity mistake: When Agent Ward goes onto the aircraft to find Agent Fitz and Agent Simmons having an argument, Simmons put a cup of coffee on the desk. It vanishes from the desk a few seconds after she does this. (00:15:40)
