Our Take On John Lithgow Playing Albus Dumbledore

It Raises Numerous Questions About The Show

Lithgow is a surprising choice on many levels to be the next Dumbledore after seeing the role previously played byRichard Harris, Michael Gambon, and Jude Law. Rylance seemed like the perfect choice given his ability to play many characters who have been benevolent, wise, or eccentric.Lithgow tends to excel at playing characters who are sinister, comedic, or a combination of both. Dumbledore has his flaws and makes some questionable choices, but he is not a sinister character, and his sense of humor is a stark juxtaposition from Lithgow’s usual comedy.

Based on the memorable characters Lithgow has played inDexter,Shrek,How I Met Your Mother, and many of his other projects, he does seem like the best choice to play a book-accurate version of Dumbledore.
