Michael Dunn - unusual detective

His was a familiar face on film and on television a couple of generations ago. Michael Dunn suffered from dwarfism and was only 3'11" tall. As he put it, he did not suffer from a lot of competition for his acting roles. According to the IMDB website, while he was waiting for his big acting break, one of the ways he supported himself was as a hotel detective, so he was not afraid to take on unusual occupations.
