HBO’s high-profile six-hour miniseries Lewis And Clark, starring Casey Affleck and Matthias Schoenaerts, will resume production in the spring. I hear the cast already has been informed of the new start date.

“As we looked at the schedule for Lewis and Clark and assessed the winter weather challenges ahead, we decided to remount the production in the spring,” HBO said in a statement to Deadline. “We are currently searching for a new director and director of photography. We are also in conversations now with the actors’ representatives to coordinate their schedules for next year.”

The decision to resume filming next year comes three weeks after the pay cable network shut down filming on the project temporarily after a rough early going, with internal as well as external, weather-related factors, impacting the production. “For creative reasons, director John Curran and director of photography Rob Hardy will be leaving the production,” HBO said at the time.

Calgary, where the mini is being filmed, is currently under heavy smoke alert as wildfires have been raging in the area.

undauntedcourageBased on the book Undaunted Courage by Stephen E. Ambrose, Lewis And Clark tells the story of America’s first contact with the land and native tribes of the country west of the Mississippi River. The miniseries follows the epic journey of the Corps of Discovery and its captains, Meriwether Lewis (Affleck) and William Clark (Schoenaerts), who traverse uncharted territory on a mission to deliver President Jefferson’s message of sovereignty as they search for his fabled all-water route to the Pacific.

Lewis and Clark, for HBO and National Geographic Studios, comes from Playtone, Plan B and Class 5 production; Michelle Ashford, Curran and Edward Norton are the writers. Executive producing are Tom Hanks, Gary Goetzman, Norton, Brad Pitt, Dede Gardner, Tim Kelly and Adam Leipzig.
