Robert Z'Dar (June 3, 1950 - March 30, 2015) was an American B-movie actor, best recognized for his usually large chin and jawline. Z'dar's unusual facial characteristics were caused by a rare genetic condition known as cherubism. Z'Dar was perhaps best known for his roles in the Maniac Cop trilogy and Tango and Cash (with Sylvester Stallone, Brion James and Jack Palance). Z'Dar often co-starred in films together with his best friend Joe Estevez.
