Guy Lodge, Varitey:
“Sarah Gadon, Jack Reynor and Bel Powley charm in this brightly entertaining slice of imagined Royal Family history ||…] Why have a ballroom with no balls?” trilled Princess Anna in Disney’s 2013 smash “Frozen,” voicing the social (and perhaps sexual) yearnings of any number of repressed, restless princesses in the fairy-tale universe — as well as, if the delightful “A Royal Night Out” is to be believed, the young Queen Elizabeth II herself. Imagining the alternately raucous and romantic exploits of the future English monarch and her sister Margaret as they are let loose upon London for one wild night of Victory in Europe celebrations, Julian Jarrold’s brightly performed exercise in speculative history scores as a frothier, more feminine bookend to “The King’s Speech” — though it’s no less engaging or accomplished. With public interest in British princessdom at a convenient high due to a certain new arrival, this glossy Lionsgate release (less coincidentally timed to capitalize on VE Day’s 70th anniversary) should ride a dual wave of topicality to royal B.O. returns at home.” Read the whole article here.
Leslie Felperin,  The Hollywood Reporter:
“Canadian actor Sarah Gadon (Enemy, Belle) has been cast as Elizabeth, the one who would get the crown and eventually be played at a very different stage of her life by Helen Mirren in The Queen. Like the latter film, A Royal Night Out offers a fantasy version of the current monarch, a wittier, smarter, more likeably vulnerable creature except that in this story she’s bridling against the establishment, incarnated by mother Queen Elizabeth (Emily Watson) and father King George VI (a near-unrecognizable Rupert Everett), instead of trying to uphold it as she does in the overrated Stephen Frears film.“
Fionnuala Halligan, Screen Daily:
“Those expecting a King’s Speech redux should be warned: A Royal Night Out is more Notting Hill meets Roman Holiday – but by way of Dad’s Army. Bel Powley’s divine ‘P2’ (the family nickname) owes a debt to Barbara Windsor (“I’m so cheesed!”), while her mother (Emily Watson) could “murder a G&T” and her father, King George VI (Rupert Everett), is told to “sit down Bertie!”. With a nod to the future, the avid Tit Bits-reader P2 is even drunkenly delivered to Battersea in the back of a wheelbarrow; to say this is a broad comedy under-states its girth.“
