Ravenloft Part IV: Heart of Midnight (1990)

Inspired by Francis Ford Coppola, Tim Burton and Wes Craven.

Three decades after finding their way back to Barovia after The Prince of Darkness and his spawn mysteriously vanished, however not before Caltherios and the gang had to fight Vera Monkshood (Virginia Madsen) who turned out to be secretly an ally to not only the sinister vampire lord, Strahd Von Zarovich, but also the calculative and manic scientist, Dr. Silver (Robert Englund). The gang fled once they were outnumbered, but not before Vera was injured. However, the stakes get even higher as Cassandra (Molly Ringwald) and her bloodlust rises as the werewolf infection grows, but a spark of good luck came in as Renfried (Anthony Michael Hall) met an alchemist wizard that was nearby in the form of Viktor Ravensthorpe (Harold Ramis), who used to be a colleague with Silver before he slipped into madness but things have gone much darker as the sinister Strahd Von Zarovich found Vera, then killed her instantly with a snap of her neck. Later that night, Strahd manipulated Xandroth into thinking that Caltherios killed her, driving him into a cold, murderous rage as the werewolf was now hellbent on getting his revenge on Caltherios and his cohorts while Dr. Silver had other plans for Vera, making her into one of his horrific creations while Strahd and Xandroth were hunting them down, currently the gang were hiding in an opera house. Unfortunately, the inhabitants were an extension of Xandroth's family of werewolves. Will they escape alive, or die trying?..
