Robert Z'Dar He achieved his greatest and most enduring cult movie fame as the vengeful, relentless and seemingly indestructible undead New York City police officer Matt Cordell in the immensely entertaining "Maniac Cop" pictures. Among Z'Dar's other memorable roles are a prison guard in the enjoyably sleazy "Hellhole," a crazed prostitute-murdering serial killer in "The Night Stalker" (this part directly led to Z'Dar being cast as Matt Cordell), a vicious criminal who savagely beats up Sylvestor Stallone in "Tango and Cash," the Angel of Death in "Soultaker," a smooth drug dealer in the delightfully outrageous "The Divine Enforcer," and Linnea Quigley's abusive husband in "The Rockville Slayer." A popular frequent guest at horror film conventions, Robert Z'Dar has also produced several movies and continues to act with pleasing regularity in a slew of features.
