Hamm first appeared in the Season 6 finale's flash-forward as Ed, one of Leslie's employees who is even worse than Jerry and gets fired. Showrunner Mike Schur had previously expressed his desire to get the Mad Men star back. "If I have it my way, when we show what led up to that final moment in the season finale, he'll be there to pop in doing something incredibly incompetent,"Schur told E! News in April.

In addition to Hamm, Megan Mullaly, Ben Schwartz and Billy Eichner will also reprise their roles in the NBC comedy.
