The plot to assassinate Hitler that everyone knows about was on 20 July 1944. It had its Hollywood moment in 2008 with Bryan Singer’s Valkyrie, starring Tom Cruise as Colonel Von Stauffenberg. That film unfortunately arrived on the coattails of Downfall, which has since made all Anglophone portrayals of the Third Reich look dismally bogus. So it’s of note that Downfall’s director Oliver Hirschbiegel, having taken leave of his senses to make Diana, has turned his attention to the lesser-known attempt on the Führer’s life.

The 1965 film The Heroes of Telemark, documenting the Allies' mission to stop the Nazis from going nuclear, is to historical accuracy what David Starkey is to tact. Or common decency. The Saboteurs however, a Norwegian/Danish/British TV co-production, seems to be keener to explore the truth behind the mission. Or at least as much of it as is known.

From “Printemps qui Commence“ (spring is beginning) to “Springtime for Hitler"... that really is quite some intellectual leap. Patrick Mason, an experienced and respected opera director, has uprooted the tale of Saint-Saëns's opera from biblical Gaza, and has placed the first two acts in France somewhere around the time of Jean Renoir's La Grande Illusion, with Warsaw ghetto overtones.

This is a great, neglected film of Nazi Germany. After being savaged by German critics for its “subjective” and “sentimental” perspective on the Third Reich at its 1980 Berlin Festival premiere, it was released with 30 minutes slashed. This is the restored director’s cut’s DVD debut.

What strange things netsuke are. Tiny sculptures, usually made from wood or ivory and depicting anything from figures, to fruit to animals, they were first made in the 17th century as toggles to attach pockets and bags to the robes worn by Japanese men. For as long as they have existed they have been considered highly collectible, and perhaps it is this, and the rapturous appreciation they inspire in their devotees, that to me at least makes them seem hopelessly, unspeakably kitsch.

Remember the Hitler diaries? Stern and the Sunday Times were so eager for them to be true they went ahead and published even after historian Hugh Trevor Roper had changed his mind about their authenticity. Such was the hunger for stories about Nazis. It’s still there, but Die Welt was on firmer ground when – to accusations of sensationalism – last year it published extracts from the cache of letters, diaries and memos in the hand of Heinrich Himmler.

“Now I am become death, the destroyer of worlds.” J Robert Oppenheimer’s quotation from Hindu scripture is often used to signify the scientist’s rueful realisation, when it was too late, of what he had created in delivering an atomic bomb to the US military.

Filming in bombed locations around Italy and Germany, the immediate evocation of wartime and post-war moral zeros, ordinary Italian locals and American GIs playing themselves alongside professional actors: all these assets would be enough to make Rossellini’s gritty films made between 1945 and 1948 essential to the history of cinema. But cinema as vibrant life itself breathes in the pace and in most of the performances.

Saul Dibb dispenses with the first half of Irene Nemirovsky’s great novel Suite Française in about a minute. Grainy newsreel footage disposes of the Fall of France in 1940, then it’s on to the occupation of Bussy, the country town where Lucille (Michelle Williams) falls for gentlemanly German officer Bruno (Matthias Schoenaerts, pictured below with Williams).

The quotation from which this film’s title is taken runs thus: “Unless the world learns the lessons these pictures teach, night will fall.” It’s drawn from the voiceover of a documentary called German Concentration Camps: Factual Survey that was made by Sidney Bernstein as World War II drew to a close. It was a gathering of massed concentration camp footage and detailed explanations that he hoped would be shown worldwide but, especially, to the German people, so that they might consider their complicity.
