As the Royal Family tend to brush shoulders with many celebrities and stalwarts of the film screen, it is rare for them to become stars of the show themselves.
And while two actresses have previously married into the family, people are not used to seeing working royals appear on screen, reports the Mirror.
This unspoken rule was thrown out in 2009, however, when Princess Beatrice made a notable cameo in a new film about her lookalike great-great-great-great grandmother, Queen Victoria.
Due to her great interest in the famous monarch, Beatrice's mother Sarah - the Duchess of York - acted as a producer on the film.

The Young Victoria was released in 2009 and follows the life the 18-year-old Queen Victoria led in the first years of her reign.
The film showed the political contentions the Queen faced as her mother and her comptroller, Sir John Conroy, battled to get her to sign a regency order. It also focuses on her early relationship with Prince Albert.
The film stars Emily Blunt as Queen Victoria and Rupert Friend as Prince Albert. Other famous cast members include Jim Broadbent, Paul Bettany, Mark Strong and Miranda Richardson.
And Princess Beatrice has a brief but stand-out cameo in the beginning of the movie, as one of The Queen's Ladies-in-Waiting in the coronation scene. Sarah, Duchess of York’s profound interest in Queen Victoria's life and history is well-known - so much so, that she named her two daughters after her.
Beatrice was the name of the Queen's youngest daughter, and all three of Eugenie's names - Eugenie Victoria Helena - follow this same pattern. Eugenie was a granddaughter of Queen Victoria (she later became Queen Eugenie of Spain) and Helena was another of the Queen’s daughters.
Princess Beatrice carried on her mother's trend when her son, August, was born in 2021. The name August was one of the names of Queen Victoria’s husband, Prince Albert.
Prince Albert was christened as Franz Albert August Karl Emanuel. August is also potentially linked to Prince Augustus, Duke of Sussex by name.
Prince Augustus was the eccentric son of King George III and favourite uncle of Queen Victoria.
