Kevin Costner's Prime Video Civil War drama "The Gray House" has attracted a strong audience since premiering in February, and star Keith David has expressed hope that the eight-part miniseries will return for a second season. Costner, who executive produces alongside Morgan Freeman, has built a reputation for headline Western and frontier projects, and the series' warm reception adds to that track record even though no renewal has yet been confirmed.

The show follows four women who turn Underground Railroad operatives into spies during the American Civil War, working to establish a Union spy ring within the Confederate capital in Virginia. Season one ended on a climactic note, and David, who plays Henry H. Garnet, told ScreenRant he would welcome a second season, pointing to the wealth of untold American history still to explore, though he stressed he has no confirmed details on the show's future.
