Corrected entry: When the captain's assistant tries to give him a challenge coin he claims he only carries one from his previous ship, the USS Wichita. Just one problem. The Wichita was decommissioned on February 3rd, 1947 and sold for scrap in 1959. Captain Glass is not old enough to have served on the Wichita.
Corrected entry: When they start to dive, they are leaning the incorrect way.
Correction: When you dive forward and down you lean backward. When you rise and forward you lean forward. It's part of "Angles and Dangles"
Correction: Firstly there's a more modern USS Wichita, active since 2016. Secondly the submarine in this film, the USS Arkansas, only started construction in 2018, the year this film was released, and it's hardly unreasonable for films to create fictional ships for the sake of the plot rather than use real ones.
