...den chilenske instruktør Pablo Larraín [giver] med sin impressionistiske portrætfilm ’Spencer’ os den Diana-film, vi ikke vidste, vi havde behov for.

Larraín og hans filmhold har skabt en mageløs og nærværende film om den legendariske prinsesse, uforbeholden og kompromisløs i sit udtryk.

...dances between ethereal ghost story, arch social satire and no-holds-barred psychodrama, while remaining at heart a paean to motherhood.

...Stewart gives one of the best performances of her career so far as this highly subjective version of Diana.

...Stewart effectively captures the agony of a woman so programmed and insulated that she feels she has no escape and has lost sight of who she is.

...Kristen Stewart gets under the skin of one of the world’s most famous women, at once transformative but never feeling like an impersonation.
