Audio problem: When Deb tells Angel to "look up" warning him of the security camera, Angel moves his lips as though he's talking but there is no audible dialogue. A few seconds later, his lips stop moving but then his audible lines are spoken. Then, again, there is no dialogue, but his lips move again. (00:07:15)

Audio problem: Near the end Robin's men all push barrels of oil over to to create a wall of fire, trapping the Sheriff and his guards inside the castle. When Robin picks up the flaming arrow he shoots it at the oil where it sticks firmly in the ground, but if you listen closely when the arrow hits the floor there is the sound of the arrow bouncing against stone - it couldn't make that noise if it hit the ground directly and stuck there.
