Chuck

From Stone Cold Steve Austin to Kristin Kreuk and Brandon Routh, Chuck has attracted top-notch guest-starring talent this season.

We can now confirm: that streak will continue through the end of the season.

Entertainment Weekly reports that Fred Willard and Swoosie Kurtz will guest star as a veteran spy couple on an upcoming episode. The pair will be recruited for an unannounced mission.

Willard was most recently seen on Modern Family in the role of Phil's dad. He'll reprise that character again this season.

Kurtz, meanwhile, has guest-starred on a number of shows over the past year or so, including Heroes, Nurse Jackie and Desperate Housewives.

We interviewed the actress when she played a key role on Pushing Daisies and can state for those interested: she's as nice as they come.
