Other mistake: When Lamont walks into the alley to avoid being followed by one of Khan's warriors, he makes himself invisible, and his shadow vanishes as well. It's well noted at the beginning of the film that his shadow is always visible even if he isn't. Therefore, his shadow should still be seen on the ground and give him away.
Other mistake: In the scene where Lestat and Louis are in the tavern, Lestat kills the barmaid. He says "She's as dead as a doornail, my friend", and rests her head on the table. He then drops some coins onto the table, and the "dead" woman's eyes flicker in reaction. (00:17:55)
Other mistake: When the Creature comes out of the amniotic fluid bath, he slips around and then gets caught in the chains. Victor falls asleep and then there is a sequence of shots of him and the Creature running through the laboratory. In one shot, he is kneeling by the door and pulling on Victor's coat to wear and you can see large indentations in his back and sides. These look like a rubber or latex covering to enlarge his frame that have flexed the wrong way and have become concave and appear totally unrealistic.
Other mistake: The cop says that there were six seatbelt violations, but only five people were in the car at the time it was pulled over.
Other mistake: Part 3 - The Betrayal: Fran tells Stu that she's pregnant on July 19th, and the way she tells him implies Stu is the father, and she's due in January. It's impossible. They didn't even meet until early July. Counting backwards from January, nine months lands in April. Way before the super flu even escaped. Way before the movie is set. (00:05:45 - 00:06:08)
Suggested correction: The father is her ex-boyfriend, who we never meet. This is made clear in the book, which I know doesn't necessarily count as a correction here, but we do see at the end the baby is given Fran's last name. Surely, if she thought Stu was the father, the baby would have taken his last name.
