UK stars Olivia Colman, Idris Elba and Benedict Cumberbatch are all in demand with US directors. We look at why

A sensitive, geeky youth, stuck on a lonely cattle ranch, might understandably yearn for a kindly uncle figure; someone to confide in, or be mentored by. But the companionship actor Benedict Cumberbatch offers his brother’s stepson, Peter, in the widely Oscar-tipped western Power of the Dog is a very long, precarious horse ride away from anything avuncular.

In fact, Cumberbatch’s portrayal of the emotionally thwarted Phil Burbank is a study in twisted misery. In one early scene, Burbank notices some fragile paper flowers the teenager has made to decorate a dinner table at his mother’s canteen. But, instead of praising them, “Uncle Phil” is driven to publicly sneer.
