The casting comes as production on the upcoming eighth and final season of the HBO awards darling has already wrapped production.

Veep star Matt Walsh isn't wasting any time in booking his next series regular role.

The actor and comedian has been tapped to topline the cast of the ABC comedy pilot Happy Accident.

Picked up to pilot with an early season order in November, Happy Accident revolves around two Pittsburgh families — a father named Bud (Walsh) with three adult daughters, and a hotel lounge singer with her med student son — who are forced together after a decades-old secret is revealed.

The single-camera comedy hails from Modern Family writers Abraham Higginbotham and Jon Pollack, who will pen the script and executive produce. The potential series is a co-production between 20th Century Fox TV — where Higginbotham and Pollack are under overall deals — and its soon-to-be corporate sibling ABC Studios.

The role marks Walsh's first TV gig since wrapping the HBO critical darling Veep, where he has been a series regular for all eight seasons. Production on the final run of the awards season staple has already been completed.

Repped by UTA, Walsh next has the feature Under the Eiffel Tower due out Feb. 8.
