Twilight author Stephenie Meyer added an update to her blog today after a visit to the Twilight set. She shares some nice tidbits about how she felt watching the "humans" in the cast bring their characters to life, and has a funny anecdote about a prank pulled on her by Peter Facinelli (Carlisle) over the crucial issue of what happens to food vampires eat if they ever have to pretend to eat to fool humans (kinda gross answer: they eventually have to regurgitate it!).
Most interesting to me of Meyer's thoughts on how the filming is going, though, is what she has to say about Kristen Stewart and Robert Pattinson "channeling" Bella and Edward. Meyer seems very pleased with the performances by both actors so far, and notes that the chemistry between the two is so good that fans "might want to bring a paper bag to the movie, because their on-screen chemistry may cause hyperventilation." Dang.
