Can someone explain to Sam Elliott what The Power of the Dog is about – and what movies are?

Despite more than 100 screen credits of his own, the actor sounded pretty confused about the basics on Marc Maron's podcast

For approximately a full hour, the latest episode of Marc Maron's WTF podcast goes absolutely swimmingly. The episode's guest, Sam Elliott, rumbles on amiably about all manner of subjects, and he seems to be building a genuine rapport with Maron. And then, almost as a closing afterthought, Maron asks Elliott: Did you see Power of the Dog?"

And then everything went to hell.
