Michael Berryman (born September 4, 1948) is an American actor. He is famous for having a unique physical appearance, the result of Hypohidrotic Ectodermal Dysplasia, a rare genetic condition which prevents him from developing hair, sweat glands or fingernails. By his own admission, in an interview for the DVD release of The Hills Have Eyes (the 1977 film that marked his breakthrough role), he was born with "twenty-six birth defects". He has appeared in several horror movies and other B movies.
