Other mistake: When Abbott is talking to Axel for the first time, he is flipping through a book that has files and pictures on Axel. One of them is a picture from when he got arrested after he got thrown out of the window. It is made to look like it was a picture taken of him at the time of his arrest, but it is a direct screen grab from Beverly Hills Cop.
Character mistake: Characters frequently refer to there being crocodiles living in the water. Alligators live in Florida, not crocodiles. And although they are closely related, they are not the same species.
Continuity mistake: At the fancy dinner at the beginning of the movie, Frida uses the titular line ("Blink twice if I am in danger") on Kyle MacLachlan. Rich slightly tips over his glasses as Slater waves his hand. In the next shot, Slater is still waving, but Rich's position is wildly different; his glasses are completely off and in fact below his waistline. (00:09:20)
