Madam Varcolac's name is Romanian for werewolf (sfârcolac).
Although Jordan is assumed to be the big sister, in reality Victoria Justice and Chace Ellison are only seven months apart.
Every time Madame Varcolac's name is said, you hear a wolf's howl. This is obviously an homage to "Young Frankenstein" whenever Frau Blucher's name is mentioned you hear horses braying.
Steven Grayhm, who plays Goran, is 12 years older than Victoria Justice (Jordan)
The pistol that Paulina uses throughout and at the end of the movie, is a COP .357 Derringer. The gun is no longer in service. It was also featured in other movies like Blade Runner (1982), Bad Boys : Flics de choc (1995), and Matrix Reloaded (2003). It was also used in 21 Jump Street (2012).
