In the beggining scene when the clerk and the trooper are talking about the Gekkos, the trooper states that they killed one trooper, three cops, and one civilian. But when we hear the news lady, she says they killed three troopers, five cops, and three civilians.

In the scene where they first enter the titty twister, you'll notice that the singer in the band has soaking wet hair. But during the next song about two minutes later, his hair is put back and completely dry. This occurs a few times.

In the scene where they first enter the titty twister, notice that you hear an electric guitar in the the backround, but the man is playing an acoustic guitar, and the guy next to him is playing bass. Also, a little before everyone turns into vampires, notice that his bass turns into an electric guitar and that we are now missing a bass player. Plus you can also see the acoustic guitar player holding the guitar with one hand while he's supposed to be playing, so obviously he's not.
