The Washington Post said Miller, the show's creator and star, assumes the voices of more than 50 animated characters, as well as Scottish actor Sean Connery and non-"Simpsons" Simpsons O.J. and Jessica, in about 80 minutes.
Miller plays MacBeth as Homer, Banquo as Ned Flanders, MacDuff as Barney Gumble and King Duncan as Charles Montgomery Burns.
The comic version of the Shakespearean tragedy, which the Post said has the blessing of "Simpsons" creator Matt Groening, plays at Washington's Woolly Mammoth theater through Sunday.
