World War II is finally over and all of London is preparing for a huge party. Princess Elizabeth (Sarah Gadon) and Princess Margaret (Bel Powley) would like to join into the festivities, incognito. The King (Rupert Everett) and Queen (Emily Watson) are not really convinced that it’s a good idea, but then give in anyway. Chaperoned by Lieutenatns Pryce (Jack Laskey) and Burridge (Jack Gordon) they make their way into the city. Soon enough though, they not only escape their chaperones but also lose each other. Elizabeth recruits soldier Jack (Jack Reynor) to help her get Margaret home in one piece and before their curfew.
A Royal Night Out was a sweet, fun film that takes absolutely no (narrative) risks whatsoever, transforming the royal family almost ino superhumans in their attempt to be pleasing.
