When I was a kid, I usually had a similar kind of mix up with prairie dog and prairie wolf, one being more like a groundhog and the other being the coyote. Though I feel as though prairie wolf might be a more common term here in the Netherlands.
Where Robin Wright was the common factor in the films I saw last weekend, this weekend the spotlight is hovering over Lindsay Duncan for a bit. She played an important supporting role in 'Blackbird', and had a smaller part in 'Birdman', starring Michael Keaton, Emma Stone, and Edward Norton.
