Factual error: The phone at the Peacocks house is too modern for the time - the cord going into the handset had a clip in cord versus being attached directly to the piece.
Factual error: In the movie, Marcus is out of high school, probably in his late teens, early 20's. Going by 50 cent's age, this would probably put the movie back in the mid 90's. When he flashes back, he's younger, put it in the late 80's. Well, in one sequence when he's young, he's playing with friends and has on red and white low Air Jordan 2's on. These were not made in this color until 2004. Same in another sequence when he's talking to Majestic while eating fast food, he's wearing some white and green Air Jordan 4's, which also didn't come out til 2004, which in fact is when the movie was filmed.
Factual error: When Buddy and the musicians tour bus is towed to the Clear Lake Auditorium for the final concert before the fatal air crash, the canopy states that the concert is on the 3rd of February. The fatal accident that took Buddy, The Big Bopper and Ritchie Valens occurred at 1am on 3rd February 1959 so the canopy should have read 2nd February.
Factual error: The film strongly implies that John Dudley, the Duke of Northumberland, keeps his head (literally) by converting to Catholicism. In fact, he was executed well before Lady Jane Grey was.
Factual error: Just after the start of the Korean War, McArthur places a map of Korea on the hood of a jeep to explain to a subordinate general his plans to invade Inchon. The map shows the boundary of North and South Korea not along the 38th parallel, which was the border at the time (1950), but along today's DMZ - not established until the Korean armistice was signed in 1953.
Factual error: At the end of the film, Mary Magdalene approaches Jesus just as he has arisen from his tomb, at first shocked that he has arisen. As Jesus is talking to her and motioning with his hands, it is plainly clear that he has no nail marks/stigmata, when he should have. (See John 20: 24-29, where-in the resurrected Jesus shows "Doubting Thomas" the nail prints in his hands.)
Factual error: When Richard asks Art his opinion of his book, a copy of "Haymarket Scrapbook" is on a shelf. This book was first published in 1986, yet Richard's book will be published in 1981. (01:03:00)
Factual error: The queen's maid tells Brown that the queen is currently reading 'Lord Tennyson.' That would be difficult in 1864, as Tennyson did not accept a peerage until the early 1880s.
Factual error: Towards the beginning of the film, the Cashes receive a notice about their rent. It's the 1950's and the address has a ZIP code. ZIP codes were not introduced until 1963.
Factual error: The song "I Won't Dance" was not written until the early-'30s, at least six years after the time it was shown being used in the film. However, it is still performed in the dining room scene.
Factual error: A 1950 Chevrolet and a 1950 Oldsmobile can be seen in street scenes in this supposedly 1944-set movie.
Factual error: The view from the aircraft Jane is flown home from France in shows the modified double engine pod of the 747 famously at Dunsfold Airfield, Surrey. Also a late livery grey RAF VC-10 parked in the distance. Also the engines of the plane she is in are upgrades and not right for the year it is supposed to be happening. (01:23:20)
Factual error: In a picture from the UN headquarters in New York in the year 2003 you see two German flags. The German Democrativ Republic hasn't existed since 1990. (01:16:04)
Factual error: The scenes set at Wrestlemania XXX (2014) were filmed at a RAW show in 2018 - fans are visible in the background wearing wrestling merchandise more recent than 2014.
Factual error: The scene that takes place at the Ford release of their 1971 models has two Mustangs driving to the event. The one in front is obviously a 1973.
Factual error: Julia Child's address on the envelope that she received from publishing company Alfred A Knopf contains a zip code. The envelope contains a letter informing Julia that Knopf wanted to publish her cookbook. That first cookbook, Mastering the Art of French Cooking, was first published in 1961. The US Post Office didn't initiate zip codes until 1963.
Factual error: Hugh Jackman says the car he is working on is a '72 classic. It is actually a 1979 Pontiac Firebird.
Factual error: When Bonnie and Clyde are killed he is lying on the ground in front of the car, and she is in the driver seat. In real life they were both killed in the car. He was in the driver seat, and she was lying up against him. (01:44:20)
Factual error: A concrete barrier is shown around the White House in the 1960's. This was not put into place until the 1980's.
Factual error: During Howard's "Thank You" speech to New York he gives NYC the gift of a live performance by AC/DC. The year was 1985. As the band takes the stage and launches into "You Shook Me All Night" we see Phil Rudd on drums. Rudd had quit AC/DC two years earlier and was replaced by Simon Wright. (Rudd returned in 1994, hence being part of the band when the scene was filmed).
