“Every war is different until it’s the same…” The BBC and PBS have unveiled the first trailer (below) for period war drama World on Fire.

Helen Hunt and Sean Bean star in the series, written by The A Word’s Peter Bowker and produced by Victoria producer Mammoth Screen. Launching later this year on BBC One and recently acquired by the U.S. public broadcaster for its Masterpiece strand, the series is a multi-stranded drama that looks at World War II through the eyes of ordinary people from all sides of the conflict.

The first seven-episode season will follow the first year of the war, starting with the German invasion of Poland in September 1939 and ending with the Battle of Britain.

The cast also includes Lesley Manville (Mum), Jonah Hauer-King (Little Women) and Julia Brown (The Last Kingdom), Polish Academy Award-winner Zofia Wichłacz (Warsaw 44) and Brian J. Smith (Sense8) along with Parker Sawyers (The Autopsy of Jane Doe), Tomasz Kot (Cold War), Bruno Alexander (Eden), Johannes Zeiler (Faust) and Eugénie Derouand (Genius).

World On Fire was developed by Mammoth’s Creative Director Rebecca Keane and executive produced by Bowker, Damien Timmer, and Helen Ziegler for Mammoth Screen, Lucy Richer for the BBC, and Rebecca Eaton for Masterpiece. The Series Producer is Chris Clough. Adam Smith (Trespass Against Us) is directing episodes one and two, Thomas Napper (Jawbone) is directing episode three, Chanya Button (Burn Burn Burn) is directing episodes five and six, and Andy Wilson (Unforgotten) is directing episodes four and seven.

ITV Studios Global Entertainment handles global distribution for World on Fire.
