American actor Michael Berryman, known for his striking physical appearance, has appeared in numerous horror films. The Los Angeles native was born with hypohidrotic ectodermal dysplasia, a genetic disorder that affects the normal development of hair, skin, nails, teeth and sweat glands. Working as a florist before beginning his acting career, Berryman's first film role was a minor one in the 1975 adventure "Doc Savage: The Man of Bronze." In the same year, he took on a small role in the Academy Award-winning drama "One Flew over the Cuckoo's Nest." Berryman gained recognition for his role in Wes Craven's 1977 horror film "The Hills Have Eyes," playing a member of a clan of deranged cannibals living in the wilderness; he reprised this role for the film's 1985 sequel, "The Hills Have Eyes Part II." The actor made a lucrative career out of playing evil, monstrous characters in various films, including the 1985 teen comedy "Weird Science," the 1990 horror film "Evil Spirits" and Rob Zombie's 2005 horror thriller "The Devil's Rejects." He has also made guest appearances in numerous television shows, including the horror series "Tales from the Crypt" in 1991, science fiction show "The X-Files" in 1995, and the action-adventure series "Conan" in 1998.
