Factual error: The police Lieutenant Hightower is wearing the rank of Captain.
Factual error: The accident takes place the night of July 18, 1969, and they show there being a full moon. That night the moon was actually waxing crescent with only 14% visible, and set at 10:27pm while the accident happened about 12:45am, so there was no moon in the sky anyway.
Factual error: The black leather chair of the Home trust banker is more modern than the movie setting in 1922. (00:59:35)
Factual error: The film informs us the gravity on Neptune's moon Triton is less than 8% of Earth's. But the whole physics of the rocks and his movement on the surface do not reflect that. The actual surface is frozen nitrogen. The difficulty he has in moving around is not well correlated by him only weighing 7kg. Https://www.imdb.com/title/tt5361488/.
Factual error: The family's roadtrip was during "summer vacation", but there was intermittent Fall foliage (yellow, orange, red leaves) during their four days traveling. Quite often, the foliage was closer to what would be expected in late September or October and even November.
Factual error: In the beginning of the movie, during Dickens' visit to America, you can hear them playing the melody from the song "I'm a Yankee Doodle Dandy" written by George M. Cohan in 1904. This was 61 years after the events in the movie. In the ending credits they cite this as "Yankee Doodle Dandy" which was written many years before. But, that was not the melody that was being played.
Factual error: Performing for Queen Victoria is the famous opera composer Giacomo Puccini. This happens during her sojourn in Florence in 1888. Puccini was born in 1858, so he was barely thirty years of age, but the actor portraying him, Simon Callow, is in his late 60s (and it shows). Moreover, he is presenting his latest creation "Manon Lescaut"; in 1888 he hadn't even started working on it.
Factual error: For a movie about the Amazon Basin, it is too bad they pictured many birds from the zoo or computer generated "who knows what." They used a Great Hornbill and African vultures (griffons or white backed vultures) - not South American. They also used computer generated white birds flying over River in "V." Could have been a flock of Cattle Egrets, but just was not right for them.
