Spartacus: Blood and Sand

Legends - S1-E3

Continuity mistake: At the gladiatorial school, Gnaeus throws his net over the stake. While he's trying to take it back Spartacus talks to him, and then in the next shot the net suddenly appears around his arm. (00:25:25)

Mark of the Brotherhood - S1-E8

Continuity mistake: Near the start, right after Spartacus slices a man, you see him holding only the hilt of a sword - when shots of cutting are seen, the blades are normally added digitally, but it wasn't in this case. A couple of seconds later it is back to a full sword. (00:01:40)

Victory - S3-E10

Continuity mistake: During the final battle there is a long trap between the armies, filled with spears and hidden, where the Romans fall when trying to get to Spartacus' army. Before the Romans pass into it, a messenger from the Roman army comes through on his horse without falling into this long continuous trap.

Delicate Things - S1-E6

Other mistake: In the scene where Barca is bleeding at the pool, Batiatus comes and grabs his hair. Barca abruptly moves before Batiatus starts to actually pull his hair.

Spartacus: Sura and I often spoke of children. A family we were going to have now forever denied me. As I now deny Glaber of his.
Ilithyia: The child is yours.
Spartacus: You lie.
Ilithyia: Would then my tongue make false noise? It yet speaks bitter truth. Monthly blood ceased after you came to me in Batiatus' villa. Lucretia had promised Crixus - a cruel jest. Tis a memory that lingers, is it not? Of that night. Of you inside me.
Spartacus: Yes. As does memory of my hands around your throat.
