Other mistake: At the beginning of the film, Vida and Noxema (co) win the local pageant and advance to the national level, taking ChiChi with them as a passenger. At the end of the film, ChiChi wins the national pageant for which she was not a contestant.
Suggested correction: Vida and Noxema winning the "local" contest (New York City's "Drag Queen of the Year") did not mean they "advanced" to the nationals. They simply won a paid trip to Hollywood where they could then compete in the "Miss Drag Queen of America" pageant. However, anyone could enter the pageant.
Other mistake: At the end of the play, Arbuthnot picks up a newspaper in the dining room and reads an article with a headline about disappearing local people (referring to those the graduates have killed). However, the actual body of text in the article is talking about politicians voting to halt construction of a new Hadron Collider.
Other mistake: At the club, Sid likes the blue suit and takes it. But he is still wearing the suit he came in when Denzel's character shows up and is not carrying the blue suit as he leaves. If he somehow had it concealed on him it would have been shot up when he was thoroughly shoot. Yet when we next see Sid he is wearing the blue suit and there is not a mark on it.
Other mistake: When Malagant visits the Round Table, he places his sword at his old position but never retrieves it before he leaves.
Suggested correction: Near the start of the film, when Malagant and his men kill villagers and burn the border village, Malagant wields his current distinctive sword with its long serrated edge. So when Malagant places his own old "Knights" sword (all Knights of the Round Table have identical swords) at his past position on the table, Malagant effectively renounces his former seat at King Arthur's Round Table. Prince Malagant has absolutely no intention of retrieving that sword when he exits.
Other mistake: When in the jungle, Elliot says to Amy "Let's turn your volume down" and makes an adjustment to Amy's backpack voice synthesizer. A few seconds later Amy "speaks" at exactly the same volume as before.
Other mistake: When Durant and his men chase Lauri out on the streets, they are waving around their guns and causing great commotion and panic amongst bystanders. However, in certain wide shots, you can see some of the extras are standing still, and not reacting to the chaos as they were in previous shots.
Other mistake: When Angela arrived at the hospital to see Alan, the nurse behind the nurses station tells her "we have him intubated and pumped full of epinephrine." When Angela enters Alan's hospital room, he is not intubated.
