Character mistake: When the Tradewind arrives at the island, captain Hilliot says, "They might not be civilized," to which Richard replies, "Civilized: c-i-v-i-l-i-Z-I-D."
Character mistake: When Hook has Pan under control, the kids start to say "I believe in you" in turns. The second one, a red haired boy, can't help staring at the camera.
Character mistake: When Mike fights by the concession stand at the mall, the Reuben sandwich is misspelled on the menu in "Rueben." (00:06:35)
Character mistake: We see in a flashback (so, early 1600s) the protagonist with his mother in Ruen, back in motherland France. She tells him she is praying to St. Joan (d'Arc; they are in front of a statue of hers). Joan d'Arc wasn't canonized until the 20th century. You could argue that in the eyes of the laymen she was already considered a saint. However, her son does not object and considers her a saint as well, doubling down on the statement even later on in Quebec when he does not have to humour his mother, and he is a Jesuit. He obviously should know better. (00:35:25)
