Megan Mullally and Nick Offerman are set to join the final season of The Umbrella Academy. It has been revealed the pair will play married couple Drs. Gene and JEan Thibedau in the fourth season of the superhero Netflix series. Comedian David Cross will also join them, playing shy business owner Sy Grossman.

“I mean, the deal’s not quite closed but let’s just pretend it is,” Mullally revealed to Entertainment Tonight during the premiere of Season 3 of Party Down in Los Angeles. The actress added that she and her husband, Offerman, will begin filming “in a couple of weeks.” Mullally and Offerman will portray “a mild-mannered married couple named Jean and Gene, who are college professors.” Further cast additions to the fourth season of The Umbrella Academy are also expected, with production having already begun for the main cast earlier this month.

Both Mullally and Offerman have a long career in acting, spanning several decades. Mullally is best known for her role as Karen Walker in the hit television comedy, Will and Grace, voicing Sarah Wiggam on The Simpsons, and, more recently, for her role as Lydia Dunfree in Party Down. Offerman, who also appeared in an episode of Party Down and leant his voice to The Simpsons character Captain Bowditch, has been catapulted into the spotlight after playing survivalist Bill in HBO’s The Last of Us. Cross is a multi-hyphenate perhaps best known for his work alongside Bob Odenkirk on the sketch comedy series Mr. Show, and as Tobias Fünke in the comedy series Arrested Development.
