Gandalf: Wizard and Beard Enthusiast
Sir Ian McKellen reprises his role of Gandalf the Grey, a very powerful wizard who arguably invented the ZZ Top beard. He is capable of making hobbits do just about anything he asks of them, especially if it concerns saving the world. Gandalf is a key player in both 'The Hobbit' prequels and in the original 'LOTR' films.
