First of all, I just noticed this, from an ad in Fangoria - Spencer's Gifts will be selling... "Seed of Chucky" doll! Whoooot! *L*!
Some tidbits from various magazines - SPOILER WARNING!!! Anything in brackets is my own commenting:
[ETA: The quotes below are not Billy's - they're from various people involved in the production.]
(talking about filming locations): ..."a little bit in England at first because that's where we pick up on Glen - the kid we saw born at the end of "Bride" - as a Dickensian orphan that's been enlisted in a kind of show-business slavery by a ventriloquist who's making it seem as if he's this great ventriloquist, but it's only because he has this doll that's really alive."
"In essence, the battle over the sex of their child is a big issue in the movie because Tiffany wants a girl while Chucky wants a boy." [note: the "child", like most dolls, is "not anatomically correct" - hence some gender confusion!]
There's some discussion on how they made the child as androgynous-looking as possible, and how the crew seemed to get rather protective of "Glen", and then some comments about Billy Boyd's part:
"But one of the things that I think really helps sell the character is Billy Boyd's voice performance."
"For the next shot, Glen walks up to Chucky and Tiffany, who are at this point just lifeless dolls lying on a table, and the frustrated child then pleads with them to wake up. As the camera rolls... the sound of Boyd's voice fills the stage: "Look! I still have the necklace you gave me. I've always wanted to know - what do these words on the back of it mean? Is it our family motto?".... The incantation immediately revives Chucky, who takes one look at Glen and coldly says, "Yikes! Who the hell are you? It looks like the kid fell off the ugly tree and hit every branch on the way down. You gotta feel bad for the parents." Glen is profoundly crushed. [I can just imagine how heart-breaking Billy can make this]
"Chucky is this very conservative, chauvinistic male figure. And Napoleonic, too, because he's in this little body. For him to have a child who is the opposite of him, a child who is very sweet and innocent, unthreatening, and unsure of his own gender and sexuality..."
"I wouldn't say that I was thinking of him exactly as gay, because he's written as a presexual child for whom those issues have not yet arisen in life. I didn't think of him as gay so much as of a "third sex". He's not effeminate, he's just open to everything."
