Michiel Huisman from Game of Thrones will join the Discovery Channel series Harley and the Davidsons. The show is based on a true story and tells how two 19-year-old boys, William Harley and Walter Davidson, opened a company in the backyard in Milwaukee and, after some struggle, established the world-famous "Harley" brand. Michiel Huisman plays Walter Davidson, and he plays Daario Naharis in Game of Thrones.
