Manuel Conde was the first to play Genghis Khan (according to IMDb). Manuel was born in the Philippines which, I guess, is the closest to Mongolia than any other actor.
Marvin Miller in THE GOLDEN HORDE
In possible the strangest casting decision ever, John Wayne played the legendary Mongolian ruler in THE CONQUEROR that bombed at the box office.
Ronaldo Lupi played Genghis Khan in two movies: THE MONGOLS (above) and below, HERCULES AGAINST THE BARBARIANS
Lastly, there's Egyptian actor Omar Sharif in another inaccurate adaptation in GENGHIS KHAN
