Me: it's Avatar with beavers.

Wife: what are you talking about?

Me: Hoppers. It's Avatar with beavers.

Wife: yes, I understand the individual words.

Me: <shows the trailer>

Wife: oh. It's Avatar with beavers.

@TomF There's a joke in one of the trailers where a character says, "So it's like Avatar", and the scientist takes offense.
