Corrected entry: During the bar scene (at the Moor Bar)...Cuba Gooding and Robert DeNiro challenge each other to holding their breaths in Mark V diving helmets filled with water. The Mark V diving helmet is not designed to hold water in like that. The water being put into the helmet would rush out all over their shoulders. You would need a neck-dam to accomplish that feat. Mark V's were never made with one. Only the newer helmets such as the Miller, the Superlite 17 or the Superlite 27's have them.
Corrected entry: The aide is first referred to as "Lieutenant Hanks" by the ship's captain. Then, he's shown wearing rank insignia of a single silver bar on his collar. In the US Navy, that's the rank of an Ensign. As a lieutenant in the Navy, he should be wearing two joined silver bars (same as an Army Captain). (00:16:25)
Correction: Ensign is a single gold bar. A single silver bar is Lieutenant Junior Grade.
Corrected entry: In the bar scene, we see Rourke at the bar. He is wearing his medal of heroism, but when he goes over to speak to Gwen (Charlize Theron), the medal is gone.
Correction: Rourke is never actually wearing his medal in the bar scene. He's looking at it while holding it in his hand, contemplating whether or not he actually deserves it. When Carl and Gwen enter the bar his hand drops out of frame, probably putting the medal in his pocket.
Corrected entry: Cuba Gooding plays a Boatswain's Mate, but wearing his rate on his left sleeve. Boatswain's Mate was a "right arm" rate; the emblem should have been worn on his right sleeve.
Correction: Depends on the time frame. The badge was moved to the left arm in 1949. Thereafter, there were no more right arm rates in the USN.
Correction: Yes, but they didn't run back to the base and grab helmets, they were already at the bar. Obviously it's a bar frequented by divers and the helmets have been modified for this contest.
