Continuity mistake: When Kadgar is telling Lothar about the great gate and that the Guardian burned his research, both of them go to pick up a chest, which they were doing anyway, but instead the scene switches to them both sitting down to talk, and the chest has gone. (00:52:00)
Revealing mistake: In the opening scenes, we see a very pregnant Draka reclining on a bed of animal hides as Durotan watches over her. In the extreme closeup, we see Draka twitch her lips, and her small tusks flex from side-to-side with her lips, instead of remaining firmly aligned with her jaw as they should.Charles Austin Miller
Trivia: When a human warrior is pulled from his horse and thrown to the ground by an orc during the first battle between the orcs and the humans, he yells a Wilhelm scream.
Medivh: I'm sorry old friend. Seems I have let the Orcs into this world. The Fel... just twisted me, I... don't even know what else I may have done. I just... don't remember. Everything I thought to protect I have... destroyed. I can't control the Fel... no-one can.
