Factual error: A native French speaker like Monique would never mistake the word 'testicle' for 'tentacle'. The French word for 'testicle' is 'testicule' and the word for 'tentacle' is 'tentacules' - both are pronounced almost identically to the English form. She'd have to confuse the two words in French, and not even a non-English speaking French person would make a mistake like that. Monique's English is very good. She'd be perfectly aware of what she was saying.,.
Factual error: The tiny missiles on the F16 are shown as being attached to some sort of flexible metal framework which bends and shifts as the plane moves along the ground. The F16 is a supersonic fighter - any such thing would be ripped clean off the wing at speed. The missiles carried by the F16 are attached to streamlined 'hard points' under the wing, or the wingtips themselves.
Factual error: When Rachel and Samuel leave for Philadelphia by train the train overtakes Daniel's cart after quite a while. That's not possible since Daniel was still standing on the platform when the train left the station. (00:08:45)
Factual error: The KGB agent hunting Jonathan is carrying a Spanish Campo-Giro pistol. There's no way a KGB agent would carry a foreign sidearm in a Soviet Bloc country, especially one that was phased out of service in the late 1920's.
Factual error: When John Cusack is talking to Daphne Zuniga in the swimming pool, watch for the view of the window. There is a palm tree growing at this Northeastern, snow covered college campus. (Obviously an oversight when filming in California, but a mistake nonetheless.)
Factual error: In the shot of Florence with several bridges and the river shown, cars and motorbikes can be seen going across the lowest bridge in the shot. (00:10:10)
Factual error: There is a scene in which the Catholic high school boys are lined up to go to Confession to a priest. One of the minor characters is a compulsive masturbator, a recurring gag in the film. He is trying to estimate how many times he has wanked since his last Confession, and Kevin Dillon's character takes out a digital calculator to help him figure it out. The film is set in 1965, about 8 years before personal calculators hit the market. (I was precisely the age of the characters in 1965, and we would have sold our souls to the devil for such a device. It was still science fiction!).
Factual error: The hawk that Isabeau turns into is a red-tailed hawk. Red-Tailed hawks are a North American Species and wouldn't be found in Europe.
Suggested correction: There is nothing in the film to suggest that because they live in Europe, Isabeau should only turn into a hawk native to that continent. It's a magical curse. A film can make its own rules how magic works in their universe and in this film Isabeau is cursed to turn into a North-American hawk for whatever reason.
Factual error: Swain was leading to Shute 9-13. He got an escape, then a takedown, then a fall. The score should have been 12-13 when he got the fall, but the scoreboard still showed 9-13 after the match when he was celebrating with his team. (01:43:33)
Factual error: When Kirby sees Dale at the ER, he says "You were a senior when I started at Georgetown." That's just three years between them and the gang just graduated from Gtown a few months ago. Dale should still be in med school, years away from becoming a doctor.
Factual error: Quatermain and Jessie are on the roof of the caboose of the train. The train engineer slams on the brakes because there are elephants on the tracks. Instead of being flung forward as the train slows, Jessie is flung towards the rear.
Factual error: When Anthony Michael Hall is being pursued by the police, they have the logo of City of Los Angeles, but this takes place in Chicago. (01:18:40)
Factual error: During the movie they play two Patsy Cline songs, Crazy and Leaving On Your Mind.Problem is Desert Hearts is set in 1959.Those two songs were released several years later, Crazy in 1961, Leaving On Your Mind in 1963.
Factual error: During the scene where the laser is used to heat the popcorn in Hathaway's house, the laser hist the ground, works its way up the side of the house and then settles on the window. At that point it stops moving. This seems impossible since the laser is being fired from a moving airplane and would constantly need a slightly different angle in order to keep hitting the house in the same spot.
