Which reminds me of some of the chat from the producers on the soundtracks.
When Gandalf first sits down at Bilbo's table, he bumps it, but Bilbo's "half" of the forced -perspective table doesn't move.
And yes, there was a car moving along the horizon as Sam and Frodo were walking across the field leaving the Shire. It was digitally removed for the EE version of FOTR. (Spoilsports).
They also mentioned the day of panic when they got an email from their dwarvish language expert. Balin's tomb is supposed to be decorated with dwarvish place names, but he said some joker wrote, "Bob was here" in dwarvish among the rest of the lettering. They were deathly afraid that the "single framers" would spot it, so more emails flew back and forth, asking exactly where it was.
Finally their "expert" admitted he had fourth-hand hearsay that one of the set painters put it in. They brought him out to the set, and he went over every inch of lettering, but all was as it should be.
I'm hoping the 'expert' left it in and grinned all the way home :~D
You know... speaking of PJ... I heard an ad for King King today, and it said "From the Acadamy Award winning Director of Lord of the Rings" and I was just so happy for him to be able to say that, and have that bit of glory from his LoTR effort. Even if he did squander it on a monkey movie :~D
Ha! Would have been hilarious if that had really slipped through!
