Of all the professors that Harry had during his student days at Hogwarts, Alastor “Mad-Eye” Moody was one of the strangest ones: from his sloppy appearance and his fake glass eye, to his irreverent, twitchy attitude, there was nothing ordinary about this man. Brendan Gleeson’s looks and character, aside from those of this strange wizard, are actually very sweet. When he’s not acting, the actor likes to play the mandolin or fiddle. He has appeared in many movies, including Scorsese’s Gangs of New York.
