3. Michael Berryman
Michael Berryman is an American actor and his familiar face is no stranger for any fan of horror movies. Berryman has hypohidrotic ectodermal dysplasia, which is indicated by lack of sweat glands and body hair. He originally wanted to be a veterinarian, but gave up the dream due to partially insensitive fingers. Berryman worked as a florist before someone offered him to play as a cameo, in Doc Savage. He regularly appeared in various movies to play as mutants, monster or any kind of character with deformities. His physically scary appearance allowed him to play many roles with minimal make ups.
