Visible crew/equipment: After Conan is set free from slavery he finds a cave where he removes a sword. When he climbs out of the cave you'll notice someone's hands near his feet pushing up his shackles. (00:29:25)
Continuity mistake: When Thorgrim gets the wooden spike through his body, a fist full of blood splashes on the rocks behind him. The blood is suddenly gone in some shots. (01:48:30)
Revealing mistake: While the trio of thieves are using rope to climb up the wall of the Tower of the Serpent, we can see Valeria's and Conan's individual carabiners attached to the climbing cable apparatus (I'm providing my own screenshots for my mistake). (00:41:35)
Visible crew/equipment: After Conan retrieves his father's now broken sword, it cuts to Doom's temple. In some versions the first long shot is a side view of the temple, with Doom standing alone on the balcony in front of the hanging tapestry. Then, in the next long shot facing the front of the temple, there's a crew member near Doom who is dressed in black, hunched over, standing beside the tapestry, and this person is wildly gesturing to come on up, just as a high priest walks up the long stairway (before his close-up). (01:56:35)
Revealing mistake: At the Tower of the Serpent, after Conan and Subotai steal the Eye of the Serpent and also kill Doom's giant pet snake, Conan and Subotai make their escape; and when Valeria grabs the rope for her own escape, we can see the stunt cable used to lift her (I'm providing my own screenshots for my mistake). (00:48:05)
Revealing mistake: When Valeria cuts a soldier's throat, a protective pad over his belly protrudes under his shirt.
Continuity mistake: When Valeria fights a guard, his helmet falls off. A second later, she beheads him, and his helmet is back on.
Revealing mistake: When Conan is fighting in the ring and smashes a guy's body against some [prop] rocks, the painting cracks and falls off.
