Halt and Catch Fire's season-three system patch contains a fix for the AMC drama's previous lack of Matthew Lillard, Entertainment Weekly reports. The Scooby-Doo star will play Ken Diebold, a "a slickly dressed, self-assuredly confident, undeniably cool" Silicon Valley bigwig who crosses paths with Lee Pace's Joe MacMillan. The third season of Halt and Catch Fire will take place in spring 1986, which is only a few months after the Lillard-starring SLC Punk! was set. Matthew Lillard: playing every '80s archetype.
