Prolific comic actor Fred Willard died Friday night of natural causes at age 86, his representative told Rolling Stone. Willard was best known for his work in several of director Christopher Guestâs renowned mockumentaries, including This is Spinal Tap and Best in Show. Guestâs wife, Jamie Lee Curtis, was one of the first to mark Willardâs passing, tweeting: âHow lucky that we all got to enjoy Fred Willardâs gifts. He is with his missed Mary now. Thanks for the deep belly laughs Mr. Willard.â Willard received four primetime Emmy nominations in his more than 50-year career, most recently for his role as Frank Dunphy in ABCâs Modern Family. He had scene-stealing roles in Austin Powers, Anchorman and Harold & Kumar Go to White Castle.
