The Vision - S4-E12
Revealing mistake: Two oarsmen (or rowers) in Ragnar's boat, the first in front of us and the second from the back, pretend to have an oar but have none. (00:38:35)
Revealing mistake: The battle has Lagertha fighting skeletons, but on her final skeleton she swings her sword downwards and massively misses it by a large margin, but it still falls.
Revealing mistake: When they are spearing fish near the start, a water drop goes from the water to the spear, showing that it is reversed. (00:04:34)
The Message - S5-E7
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)
Revealing mistake: Even though the Vikings are rowing their boats at full speed, there are no wakes from the aft nor waves from the bows as the boats plow through the water.
