Mitchell Donald “Mitch” Hurwitz is an American television writer, producer, and actor. He is best known as the creator of the television sitcom Arrested Development as well as the co-creator of The Ellen Show. He is also a contributor to The John Larroquette Show and The Golden Girls.

Variety asked Hurwitz to reminisce about working with Walter on “Arrested Development” and he immediately responded with a few thoughts typed through tears:

I’m stunned and so very sad to hear this news. Jessica was one of the sharpest, funniest people I’ve ever worked with — and I’ve been incredibly fortunate in working with some true greats. She was, to me, the best kind of comic actor — one who’s fearless in her willingness to draw upon the, shall we say, less desirable aspects of our character that, well … make us funny. She effortlessly sunk her teeth into depicting a type of mother that, given how people related to her, must be more common than is usually celebrated.
