Continuity mistake: When Conan first fights Remo, Conan places a blood stain on his forehead by pressing his sword to it. Remo then runs off, and Conan gives chase immediately, pausing only to get Tamara on his horse. The stain is still there when Conan mounts his horse. The next time we see them, Conan and Tamara is still chasing Remo, but now Conan's face is completely clean. It is highly unlikely he would pause in pursuit of one of his father's killers to wash his face. (00:47:55)
Continuity mistake: When Marique summons the Sand Soldiers to attack Conan, a punishing blow knocks Conan completely off his feet and arcing straight backwards through the air. The camera even cuts to show the arc from slightly different angles and follows Conan almost to the ground, where he will certainly land flat on his back. But, at the point of impacting the ground, the camera cuts again and Conan lands face-down.
Continuity mistake: When Conan gets born he is attached to his mother by the umbilical cord, but when his father lifts him the cord disappears.
