The way the kids lure and trap the adults in The Children is by manipulating the parents' fears and, of course, their love. The idea that children might use their parents' love as a weapon against them seemed wonderfully twisted to me. Their MO would be about using their cries and whimpers and their innocent eyes to entrap the parents. The creepy-cute sounds of their toys would also be a useful luring device - sort-of like Hansel and Gretel in reverse. Only when the adults are totally disabled by their instinctive desire to protect the kids, is it the right moment to strike.

The aggression in the film evolves organically from the children's obsessions with things like the effect of impact or 'where do babies come from?' There is often a violent subtext in kids' games that would be terrifying if it was let loose in real life. The murders in the film are all related to the childhood in some way.
