When Kitty and Carol scare Julie with the hand and sheet, Kitty is just wearing her purple jacket, but when they return to where they left their bag Kitty has a sheet on too.
When Ramar first breaks out of his tomb, Carol removes her mask showing her hair has been flattened from wearing the mask. In the next scene, her hair has returned to its '80s style.
While in the mausoleum, Carol's sneakers change back and forth between two different Nikes. At times, she's wearing nylon sneakers with suede patches and in other scenes, she's wearing white leather ones with a red swoosh.
The pose of the man with the black glasses is changed between the two continuous shots when pair comes back from the funeral.
When the pair enters photo booth, photographs don't match what is seen in previous shot.
When Carol and Kitty find Julie's stuff, it's not hers. In fact, it's their own, because they were shown leaving it there a few scenes back. Julie never left anything there.
Near the end of the film when Olivia arrives at the mausoleum, she somehow manages to enter through the front door despite the fact that it was locked by the caretaker--as was his duty. At no time during the film is it indicated that Olivia has a key or that she is even authorized to gain access in the first place.
I know it's a movie and all, but Julie was supposed to stay in the mausoleum through the whole night and when she arrives, it's still daylight. What was she supposed to do if she had to go to the bathroom? Urinate in the urn or something? There is no bathroom in the mausoleum.
In the beginning at 33 minutes , when the Caretaker of the mausoleum told the girls to leave the cemetery , he stopped his truck at the main gate cross the street, at this moment you can see a reflection of one of the crew on the driver's door of his blue truck.
