Sam Neill's accent slip?
I couldn't help noticing that sometimes his actual accent slipped in some of the scenes, like for instance when he says "Never, Never, Never... throw chips at a driver"; the way he said "never" didn't sound American at all. And then again when he says "That sweet old thing that we met downstairs isn't capable of anything worse than, dipping her dentures into her husband's beer". He sounded Australian when he said "downstairs".
By the way, this is not a criticism. Just an observation.
