Casey Spencer was a villainess from the 1993 film, Full Eclipse.
She was portrayed by Patsy Kensit.
Casey was one of the members of a vigilante police group known as "The Pack," which consisted of werewolf hybrids. Casey encounters Max Dire and attempts to convince him to join The Pack, even going as far as engaging in a sexual encounter with Max at the home of Adam Garou, Casey's lover and the leader of The Pack. During their passionate encounter, the evil Casey transformed into a werewolf by sprouting fangs and long claws.
After their tryst, Casey attempts to offer Max a serum that would make him just like her and the rest of The Pack, but Max refuses. Casey later shoots him, but then injects him with the serum, causing his wounds to heal. Later in the evening, Casey and Max go out on their own mission: tracking down one of Teague's "ice-houses." Both of them transform and burst into the crime scene, tearing through Teague’s men. The drug runners unload their weapons upon them, but to no avail, and Casey and Max end up killing the entire group. Casey returned to Adam's penthouse and faced his wrath when he finds out about what happened between her and Max. Casey ended up sexually assaulted by Adam. Later in the film, during Max's confrontation with Adam, Casey decided to be with Max over Adam, and both of them leapt out of a window to avoid Adam's wrath. The fall injures both of them, but knowing that they don't have enough of the serum to heal both of them, Casey gives it all to Max, stating that she had been trying to stay off it for a long time. As a result, Max ended up healed while Casey succumbed to her injuries.
