Charting the rise of the Milliband brother, from their left-wing upbringing to their University days, using dramatized scenes and interviews with people who knew them.

A drama-documentary presented by Alan Yentob, with Benedict Cumberbatch in the lead role. Every word spoken by the actors in this film is sourced from the letters that Van Gogh sent to his younger brother Theo, and of those around him. What emerges is a complex portrait of a sophisticated, civilised and yet tormented man.
