I noticed a couple of funny things in the course of my latest viewing of The Fellowship of the Ring last night, both during the Moria sequence.
:: Remember the famous Far Side cartoon, in which a student is attempting to enter the Midvale School for the Gifted by pushing on the front door, even though the door is clearly marked "Pull"? Well, one of the things Gandalf does when he's trying to open the Doors of Durin is to push on them with his shoulder...but when Frodo figures out the riddle and the doors open, they swing outward.
:: In Balin's tomb, when Gandalf is reading the last entry in the journal kept by the dwarves before their deaths, we get a glimpse of the very last line, in which the dwarven runes trail off in an angle scrawl across the bottom of the page. I'm sorry, but this put me immediately in mind of Monty Python and the Holy Grail: "The Castle Arrrgggghhhhh...he must have died while carving it!"
