Frodo’s Sword Glows Blue – or Does It?
Frodo acquires the sword Sting during his adventure. It was created by the Elves and has a significant advantage: The blade glows blue when orcs or goblins are nearby.
While this ability is used for quite a while, the filmmakers seem to have forgotten it by the time they reached the Mines of Moria. There, the Fellowship is ambushed by orcs. In several moments, Sting is clearly visible without glowing, even though numerous enemies are in close proximity. A classic film mistake, explained by the fact that this aspect was forgotten among the many details.
