After playing a sitcom leading man for nine seasons on How I Met Your Mother, everyone wondered what Josh Radnor would do for his next big gig. If you answered "play a surgeon named Jedediah in a PBS Civil War series," we would have sent you to the nearest mental institution to have your brain scoped. Today, we'd be calling you a psychic.

Radnor and The Returned's Mary Elizabeth Winstead will lead the star-studded cast of PBS' Mercy Street. The six-part series follows the lives of two volunteer nurses on opposing sides of the Civil War, New England abolitionist Mary Phinney (Winstead) and Confederate supporter Emma Green (newcomer Hanna James).

As noted above, Radnor will play Jedediah Foster, a civilian contract surgeon from a Southern slave-owning background. Gary Cole, Donna Murphy, AnnaSophia Robb, Peter Gerety, Norbert Leo Butz, and Jack Falahee also star.

Mercy Street will join PBS's Sunday night lineup in winter of 2016, which also includes the highly-anticipated final season of Downton Abbey.

Will Jedediah fall in love with a woman holding a yellow parasol? I hope so!
