Factual error: The movie is set in Philadelphia, but the bus at the beginning crashes at a crossroad in front of the fast food joint Admiral Submarine, a recognizable location in Brantford, Ontario, where the movie was shot. (00:05:00)
Factual error: Prince Albert was not really wounded in the assassination attempt depicted near the end of the film. Eyewitness accounts differed as to whether he pushed Victoria down to protect her or simply dived for cover himself, but neither of the two bullets fired struck either of them.
Continuity mistake: When Ahmed Alhaznawi (the tallest of the four terrorists) has just gotten through the metal detector, a pattern of light appears on the floor behind him between shots.
Factual error: During the film, there are extracts of two songs - 'The Spy' and 'Maggie McGill' - from the Doors' fifth album, Morrison Hotel. Great songs, however the film is set in 1968 and Morrison Hotel was not released until 1970.
Continuity mistake: At the beginning of the film when Georgiana is talking with her mother about her engagement, the curl running down the back of Georgiana's neck disappears and reappears multiple times.
Visible crew/equipment: When Helene Hanfstaengl says to her maid, "I'll speak to you in the morning," she stands on a cue mark in yellow tape.
Factual error: At a very early point in the film, the King says something along the lines of "....and these are your playmates". In the background is a horde of 17th century ladies boating on the Achille Duchenne water parterre at Blenheim Palace. The palace wasn't built until the late 18th century, and the parterre was not designed until 1925.
Factual error: During their transatlantic boat trip, on their way to Athens, the American athletes are having fun naming various foods from back home that they already miss. One of them claims he misses chocolate chip cookies. Oops. That particular cookie didn't exist until Ruth Wakefield invented it in 1930.
Factual error: The weapons for this film, save for the American Krag-Jorgensen rifles, British Lee-Enfield MLE rifles, and German Mauser Gewehr 98 rifles, are completely wrong. The Russians, who had Mosin-Nagants, are portrayed with Mausers. The French are for the most part correctly poratrayed with Lebel Mle. 1886/93 rifles, but a few have Berthier rifles that weren't used until 1907. The Austro-Hungarians are portrayed with a mixture of Mausers and Berthiers when they would have had Mannlicher M88/90's or perhaps Mannlicher M95's. The Japanese are equipped with Mausers and would in reality have had Muratas. The Italians have a mix of Berthiers and Mausers, but would've used Vetterli-Vitali rifles. The Chinese Imperial troops and Boxers both have Gewehr 98 Mausers. Although they did indeed have Mausers, they had the far earlier Gewehr 71's and Gewehr 71/84's.
Factual error: The attack on the OPEC meeting in Vienna takes place on December 21. Yet, when Carlos' team exits the tram, the trees are full with green summer leaves and the sun shines as it would on a high summer day.
Factual error: The plane used in the film to take Juliet back to London towards the end of the film is a replica of a Dakota C-47. She is painted with black and white "invasion stripes" on both the upper and lower surfaces of the wings - approved in May these were only widely put into use for D-Day in June 1944. After one month the upper surface stripes were ordered removed, and by the end of 1944 they were ordered completely removed. By 1946 when the film is set they would have been long gone from any serving aircraft still flying.
Continuity mistake: The wounds that Juda got on his face from the fall from the horse at the beginning of the film, disappear the very same day.
Factual error: While flying across the U.S. before the Atlantic attempt Stewart lands and exits the plane. While doing a quick inspection of the airframe he approaches the engine and puts his hand on one of the radial engines cylinders which would have still been several hundred degrees, so should have resulted in a serious burn.
Other mistake: The end credits list the cast in order of appearance, but the order of the cast list is completely inconsistent from how the characters first appeared in the movie. (02:36:45)
Factual error: In this scene several sailors attack Alice Paul and tear down the demonstrator's banners. The older sailor's petty officer rank specialty insignia featuring three lightning bolts, Radioman, was not created until 1921, four years after this incident. (01:30:35)
Audio problem: The day after Operation Mardonius, when the first set of bombs explodes you first see the explosion and then hear it after a second, then as the last bombs explode you both see and hear the sound at the same time.
Continuity mistake: Wallis is showing his idea to the doctor and draws on the sketch of the dam. Shortly after, he shows the doctor the same sketch again and the middle line we saw Wallis draw has now changed position. (00:06:40 - 00:07:50)
Factual error: Following their re-equipping at the South Essex depot, Sharpe marches his battalion across the bridge towards London. However, every non-commissioned officer is aware that troops don't march across a bridge. They break step to avoid setting up harmonics that would collapse the structure.
Continuity mistake: During the dinner scene with Bligh, Christian, Young and Fryer, watch the wedge of cheddar cheese magically change size.
Factual error: The bikes used in film are Enfield Classics, which were introduced in 2010 and not available in 1960 or 1947. The engines are visible in 2 scenes (when young Milka meets his sister for first time in Delhi and when Milka rides to see his old home when in Pakistan) and are AVL engines, not the cast iron engines in 1950s bikes.
