Childs Play
After transferring his soul, the whole thing is he’s on a limited time frame before his soul completely attaches to his temporary host and he can only transfer it to the 1st person he tells the secret to.
So why didn’t he just transfer his soul onto Andy while he was asleep? Its showed in Bride of Chucky the person doesnt even have to be alive to transfer souls, so im sure sleep isnt an issue
Movie could have been done in 10 minutes flat....
