PBS this morning unveils plans for its winter/spring TV season including a week of programming about the Vietnam War era, and Antiques Roadshow‘s first million-dollar sports memorabilia find, and an expanded Sunday night drama lineup in 2015 that means 20 new hours of Masterpiece, including Grantchester, Wolf Hall, a new Poldark, Indian Summers, and a new season of Mr Selfridge. Ditto Call The Midwife and Vicious. And, of course, Downton Abbey‘s fifth season, debuting January 4.

Phylicia Rashad is sure to take/deflect a question or two about Bill Cosby when the former The Cosby Show star participates in PBS’ Winter TV Press Tour 2015 in Pasadena to promote PBS’ new lineup. She’s one of the stars of PBS’ new August Wilson: The Ground On Which I Stand,  in which she is among those sharing stories about the late playwright and his works. Also promised for the press tour: Damian Lewis, who plays Henry VIII in Masterpiece’s Wolf Hall.

This spring, PBS will premiere First Peoples on April 29; the five-part series features the latest research exploring how early humans evolved. Highlights of anchor programs in the schedule this season include the broadcast premiere of award-winning filmmaker Rory Kennedy’s Last Days In Vietnam, presented by American Experience on Tuesday, April 28, and timed to the 40th anniversary of the fall of Saigon.
