Birdsong was one of my favorite books and one of my mom's favorites too. Not sure about the casting, but regardless I am excited. Here is the full notice from the BBC:
Eddie Redmayne (My Week With Marilyn, Richard II) and Clemence Poesy (28 Days Later, Harry Potter) star as the passionate young lovers Stephen and Isabelle, brought together by love and torn apart by the First World War, in BBC One's adaptation of Sebastian Faulks's modern classic, Birdsong.
Adapted by Bafta award-winning Abi Morgan (The Hour, Iron Lady), the two parter spans the decade of the First World War, telling the story of Stephen Wraysford, a young Englishman who, in 1910, arrives in Amiens, Northern France, to stay with the Azaire family and falls desperately in love with Isabelle Azaire.
They begin an illicit and all-consuming affair, with huge consequences for them both. Years later in 1916, Stephen finds himself serving on the Western Front in the very area where he experienced his great love. As he battles amidst the horror of the trenches he meets Jack Firebrace, a tunneller who unexpectedly helps him endure the ravages of war and enables him to make peace with his feelings for Isabelle, who he is destined to meet again.
Eddie Redmayne stars as Stephen Wraysford, Clemence Poesy is Isabelle Azaire, Joseph Mawle is Jack Firebrace, Richard Madden is Weir, Laurent Lafitte is Rene Azaire, Matthew Goode is Captain Gray, Anthony Andrews is Colonel Barclay and Marie Josee Croze is Jeanne Fourmentier.
