For the actors, working with the puppets was a lesson in patience. Katherine Heigl, one of the runaway newlyweds, says that she initially found acting with Chucky a little daunting. “I mean, what on Earth could I possibly relate all this to?” Never in my life had I had any kind of experience that I could relate back to a killing doll,” she says. “And even though sometimes you just want to burst out in laughter at the absurdity of the situation, you have to look like you're taking it seriously or no one else will, so you just have to pull out all the invisible angers and hates and feelings that there is no image for but that are there anyway and make them Chucky. “ Jennifer Tilly, though, found working with Chucky a refreshing change of pace from her usual co-stars. “The good thing about acting with a puppet is that they never get in your light, and they never try to upstage you by ad-libbing because their lines are already done,” laughs Tilly.
