The Wizard of Oz (or simply The Wizard) is a fictional character in the Land of Oz created by American author L. Frank Baum and further popularized by the classic 1939 movie.

The classic books
In the 1939 movie The Wizard of Oz, The Wizard's character is similar to that found in the earlier books: a bumbling "humbug." He was played by actor Frank Morgan. The same actor also played several other roles in the movie; including Professor Marvel, the mysterious traveling fortune teller that Dorothy meets in Kansas, the Guard at the Emerald City, the Guard at the Gates to Oz's Castle and the Coachman. His face was also presumably used as the projected image of the Wizard.
