Prime Video Snags Kevin Costner and Morgan Freeman’s Riveting Civil War Saga

Prime Video has nabbed The Gray House, a Civil War espionage drama from Kevin Costner and Morgan Freeman, with Mary-Louise Parker leading an ensemble in the true story of a covert network of women operating behind enemy lines.

Prime Video just grabbed itself a Civil War spy thriller with some serious star power behind it. Kevin Costner and Morgan Freeman are producing 'The Gray House,' an eight-part limited series led by Mary-Louise Parker about the all-but-forgotten women who helped flip the war. Expect it to hit Prime Video in early 2026.

So what is 'The Gray House'?

Based on true events, the show follows a covert ring of women working inside the Confederate capital. The core group includes a Virginia socialite, her mother, a formerly enslaved ally, and the city’s most notorious courtesan. From right under the Confederacy’s nose, they turn an existing escape network into a full-on intelligence pipeline — the kind of operation that actually moved the needle on the war.

"The Gray House is an untold true story of three amazingly brave abolitionist heroes of the Civil War, who just happened to be women."

The inside-baseball part

This one has been quietly making the rounds for a while. It was first announced back in 2022, it even opened the Monte-Carlo Television Festival in June 2024, and only now is it officially landing its U.S. streaming home with Prime Video. Translation: the series is real, finished, and now finally has a platform. Prime also rolled out the first poster, putting Mary-Louise Parker, Daisy Head, Paul Anderson, and Amethyst Davis front and center.

Bottom line
