Casey Affleck

The adventures of Lewis and Clark will continue on…at HBO.

The network greenlit Lewis and Clark, a six-hour miniseries starring Casey Affleck as Meriwether Lewis and Matthias Schoenaerts as William Clark. Michael Lombardo, president, HBO Programming, announced the news today.

John Curran is directing the miniseries, which he is also writing alongside Michelle Ashford and Edward Norton. The story, which is based on Stephen E. Ambrose’s Undaunted Courage, will follow the Corps of Discovery and its captains, Lewis and Clark, as they trek through new terrain to deliver President Jefferson’s message of sovereignty and search for an all-water route to the Pacific.

“In Lewis and Clark, we can see American idealism and the breathtaking natural beauty of the continent, as well as the complexities and tragedies of what came to be known as America’s ‘manifest destiny’,” Lombardo said. “We are tremendously excited to bring together this incredible group of talents to tell a seminal American story.”

Tom Hanks, Gary Goetzman, Norton, Brad Pitt, Dede Gardner, Tim Kelly, and Adam Leipzig are executive producing.

Production is set to begin this summer.
