At several functions, closeups of the back of the women's dresses, including Victoria's, show the slim seam line of a zipper, invented in the United States in 1851, about ten years after the film is set.
Throughout Albert and Victoria's courtship, many characters speak to Albert about Germany, which is spoken of as his nationality. Germany was a cultural region, not a unified country, until 1871, more than 30 years later. Albert's nationality would have been spoken of as Saxe-Coburg and Gotha, not Germany.
When Albert is given a portrait of Victoria for the first time, she is depicted in a white dress, with a tiara set vertically in her bun. That specific portrait was done in 1842, two years after Queen Victoria and Prince Albert were married. Furthermore, Albert designed the tiara in her hair especially for Victoria.
Throughout the film, Lord Melbourne is pronounced 'Mel-burn', like the Australian city. The title of Viscount Melbourne is derived from Melbourne Hall in Derbyshire, and pronounced 'Mel-born'. The other way did not come to be spoken until much later.
Twentieth-century hot water baseboard heaters are visible in several interior palace scenes. They are especially obvious when Victoria explains that the palace is so cold due to disagreements amongst the palace staff as to who should lay and maintain the hearth fires.
Leopold I tells Stockmar "I am the youngest son of a penniless duke". Leopold's father, Francis, was the Duke of Saxe-Coburg-Saalfeld, and hardly penniless. He was also not the youngest son; Franz Maximilian Ludwig, who lived just 22 days, was born two years after Leopold.
When Albert and Victoria have their first waltz, they slow down and stop at one point before resuming. The other dancers continue while this is happening. In reality, royal protocol would dictate that the other dancers stop whenever the queen stopped dancing.
In the coronation scene around the middle of the film, Queen Victoria is seated on the throne receiving homage and holding nothing in her hands. In the next shot, she is seated on St. Edward's Chair, holding two scepters.
At King William IV's birthday celebration, when Princess Victoria is presented to King William, she curtsies twice to the king; before the exchange between Lord Melbourne and the Duchess of Sutherland, and again after the exchange.
About 6 minutes into the film, a scene with the subtitle "Rosenau Castle, Coburg, Germany" shows snow-covered mountains in the background. The closest snow-covered mountains to Coburg are the Bavarian Alps, 350km away.
While King William IV insulted the Duchess of Kent at Windsor, some facts as shown are wrong. In the film, the Duchess sat several feet away from the king, she left the room, and neither Victoria nor the guests reacted much. In real life, the Duchess sat next to the King, she did not leave the room, Victoria cried in reaction to the King's outburst, and the guests were aghast.
The closing titles say "Victoria and Albert reigned" for a number of years. Only Queen Victoria reigned; Albert did not have this job description, as the "Thank you for reminding me..." speech shows. No husband and wife ever reigned over England together except William III and Mary II in the late 17th century.
In the film, Victoria and Melbourne are portrayed as similar in age, apparently to hint at a flirtation between them. Melboune was 38 years older than Queen Victoria, and acted as something of a father figure to the young monarch.
In the opening coronation sequence, the Archbishop of Canterbury anoints Victoria by dipping the first two fingers of his right hand into the chrism (holy oil). Anointings are done with the thumb only.
During the dinner at which the Duke of Wellington tells Victoria of Melbourne's imminent defeat, the Queen is wearing the riband of the Order of the Garter from her right shoulder. The Garter is always worn from left shoulder to right hip.
In the wedding scene, The Duke of Sussex, Victoria's paternal uncle, is about Victoria's height when he walks her down the aisle. In real life he was much taller than his niece. He'd long since shaved his mustache, and wore "mutton chops" by the time of her wedding.
According to the family tree Victoria looks at in the beginning of the film, her cousin Charlotte died in 1819, and Elizabeth died in 1820. Princess Charlotte died in 1817, inspiring the engineered royal baby boom which produced the new princesses. Princess Elizabeth of Clarence was born Dec 10th, 1820, and died 12 weeks later on March 4th, 1821.
A bloodstained Albert is carried into the palace after being wounded by a would-be assassin. There were several attempts to kill Queen Victoria and Prince Albert, but they were not harmed by any of them.
