Give Kristen Stewart all the awards now for her depiction of Princess Diana in this slice-of-life biopic set against the 1991 Christmas holiday at Sandringham Estate. Director Pablo Larrain (‘Jackie’), working from a pitch-perfect script by Steven Knight, creates a tinderbox, tosses the People’s Princess into the middle of it, and lets the embers crackle and pop until the whole place burns down. It’s a tough watch (and will, no doubt, infuriate many blueblood Anglophiles), but Stewart’s performance is as captivating as it is uncanny.
5/5 stars
