Pick of the week A lot gets packed into the 90 minutes of The Holocaust on Trial (Saturday 7.15 C4). Not only does it reconstruct (using actors) some key moments in the David Irving-Deborah Lipstadt libel case, it also uses documentary evidence and the comments of historians (Jeremy Noakes, Raul Hilberg, David Cesarani, Richard Breitman) to counter some of Irving's assertions. Powerfully directed by Leslie Woodhead, who made BBC2's Srebrenica documentary A Cry from the Grave last autumn, the documentary offers a useful outline history of the Nazis' treatment of Jews, from Kristallnacht to the "final solution" of Auschwitz.
