Larry David’s upcoming HBO sketch show about American history will feature both Isla Fisher and Jane Krakowski in guest star roles, Variety has learned exclusively.

Officially titled “Life, Larry, and the Pursuit of Unhappiness,” the show is in celebration of the 250th anniversary of the founding of the United States. The show will premiere on June 26 at 9 p.m. ET/PT on HBO and HBO Max and run for seven episodes through Aug. 7. The show stars David, some of his “Curb Your Enthusiasm” co-stars, and a roster of guest actors, as they skewer major events in U.S. history.

Both Krakowski and Fisher previously appeared in Season 10 of “Curb Your Enthusiasm.” Krakowski also recently played Mary Todd Lincoln in the hit Broadway production “Oh, Mary!”

Krakowski is a five-time Emmy nominee — four for her iconic role as Jenna Maroney on “30 Rock” and the other for her work in the Netflix comedy “Unbreakable Kimmy Schmidt.” Her other recent TV credits include “Schmigadoon,” “Dickinson,” and “Elsbeth.”

Fisher most recently appeared in “Now You See Me: Now You Don’t,” the third film in the “Now You See Me” franchise.

In television, she starred in the Peacock series “Wolf Like Me” and Seasons 4 and 5 of “Arrested Development.”
