Audio problem: In the scene when Kyle and Aaron are talking to Holly's dad, once Holly's dad has left and after Aaron has said wow, Kyle starts his sentence with the word "later", but if you look at him, he isn't actually saying anything.

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.
