Continuity mistake: Episode: "Man Hunt": When Jonas tries to interrogate the hardware store owner, the owner falls off his chair, knocking it over. In the next shot it's standing upright again.
Continuity mistake: In episode 3, "How Billy Got His Groove Back", in the scene where Mick is meeting with Eduardo on the overpass Mick's sunglasses keep switching between being up on his nose to down on the tip of his nose to being off his face and back on again.
Continuity mistake: Guy of Gisbourne says to Robin Hood that he should lay down his weapons. Robin Hood throws his bow and sword on to the ground. He then gets thrown down the cliff, into the river. A few minutes later, when we get focused on him again, we see that the bow is lying in the river with him. (00:06:05 - 00:10:55)
Continuity mistake: After running the roadblock and getting shot in the shoulder, we see Hopper's shirt with a bloody patch about 3" x 2." The camera angle changes and it is now several times larger, positioned differently and oddly-shaped (a bleeding wound would simply expand the stain on the shirt; it would not 'move'). (00:02:55)
