Other mistake: They're meant to be on rebreathers (they recycle the air around the system, so you 'rebreathe' it), yet in the u/w scenes, it can be seen that they're on open circuit systems, i.e. conventional scuba, as they're venting exhaust gases. Rebreathers do not release bubbles in the quantities shown.

Directed by: Barry Levinson
Starring: Samuel L. Jackson, Dustin Hoffman, Liev Schreiber, Queen Latifah, Sharon Stone, Peter Coyote
Plot hole: The first time they communicate with the "entity" in the spaceship, they find a correspondence between numbers sent by the entity and letters of the alphabet. The entity presents itself as "Jerry". Later on, the entity tells Dustin Hoffman, "Stop calling me Jerry" - and then Dustin Hoffman realizes that the number-letter correspondence was wrong, and the actual name of the entity was "Harry". But if that is true, how could they have communicated without problems before? The very first word that the entity used was "hello", which would have to be displayed wrong, since it begins with an "h" and has an "e".

Question: After what seems like several hours of conversation between the crew and "Jerry", did the letters J and E occur in the text before the sentence "Don't call me Jerry" appeared and Dustin Hoffman realised the translation was wrong? I haven't watched the film a second time but surely we see words that contain J and E and still make perfect sense?
Answer: I did not read the book but I will say from just watching the movie I believe Jerry was changed to Harry during the duration of the movie with the idea that Norman wanted to believe Harry was the cause of all the problems. That is why we do not see a random J in all the words that needed an H earlier in the move. Or it was a giant error on the directors part but there were a lot of unanswered questions in the move.
Answer: The "Harry" is "Jerry" has little to do with transposed letters. Norman is a psychiatrist, so by nature he likes to talk to discover new information. The entire conversation is Norman's subconscious thoughts being projected on the computer so that Norman can do his job of being the psychiatrist and talk to an entity. He has no other reason of being there. Norman is basically talking to himself. So in psychoanalysis Norman has to find a twist, which is My name is not Jerry. Ted and Harry didn't mess up the code they are too smart.





Answer: It's been a while, but as I remember it, this is explained better in the book. If I remember it correctly, since the translation program was made by Harry, he subconsciously added a section that simply mistranslated "Harry" to "Jerry". That doesn't mean every H became a J or anything like that. It only affected that word.
