We're a little more understanding of this one. When you shoot three epic movies pretty much back to back, and they're as long as the "Lord of the Rings" movies are, the odd mistake is bound to creep past tired eyes in the editing room. We're going to blame this one on the usually impeccable Sir Ian McKellan, who forgot one tiny detail when he went to put his costume on.
Here's Gandalf, ready to pitch in on the battlefield for all that is good and holy. And there, underneath the wizard's sleeve, is McKellan's wristwatch for all to see. Maybe there's a way around this one - Gandalf is a wizard after all, so maybe he magically created himself a way of telling the time years before anybody else thought of the idea. But if he could do that, why didn't he create himself a gun to fight with instead of a sword?
