Before Greg Daniels co-created Parks and Recreation and Mike Judge co-created Silicon Valley, the two writers came up with another band of lovable misfits: the middle-class Texan family of King of the Hill.

The animated series ran for 13 seasons on Fox, then aired four leftover episodes in syndication—the last one airing 10 years ago, on May 6, 2010.

Well-known actors filled King of the Hill’s main cast: Judge himself voiced Hill family patriarch Hank, Kathy Najimy voiced matriarch Peggy, Pamela Adlon won an Emmy voicing son Bobby, and the late Brittany Murphy voiced niece Luanne.

But the guest cast included tons of other famous faces, including at least five Academy Award winners. Scroll down to see those famous faces and other celebrity King of the Hill guest stars.
