From PaleyFest: Once Upon a Time's Cast and Creators Talk Fairy-Tale Twists Ahead:
•Robert Carlyle said he got his Rumpelstiltskin voice from his 6-year-old son. Carlyle said, in his thick Scottish accent, that he couldn’t imagine his voice working for the character. One day he noticed his son walking around the house talking in a funny little voice and said, "That's it!"
•Goodwin said she has to remind herself before every scene that she is afraid of Rumpelstiltskin. "It's difficult because we all love Bobby so much that I have to remind myself right before we start filming that I'm afraid of this man." She turned to Carlyle and said, "No offense, but it's kind of hard to be afraid of you!" She paused as the crowd laughed at Carlyle’s reaction: "You're so lovely and wonderful!"
•Lana Parrilla claimed her Evil Queen costumes alone get her "60 percent" into character. "The minute I put on those costumes — I mean, I can't breathe when I'm wearing them — but it really does help me create the character and stay in character. And they just continuously get more elaborate and bigger!"
•Creators Adam Horowitz and Edward Katsis gave hints about what is to come this season. "The queen and Rumpelstiltskin will now be speaking out in the open," since they recently discovered they both know the truth. "You'll find out soon who August is and what he's doing in Storybrooke. You'll also learn what Snow White did to piss off the queen very soon."
