Do see the movie if it's anywhere near you. It is more akin to great courtroom drama than to a horror film. The director professes to be an atheist, but true to history, he unflinchingly presents Sophie as a devout Christian who gathers sustenance and strength from God. (I can't imagine Hollywood even considering such honesty.) The Gestapo interrogator, Mohr, is also portrayed intensely. But note that Mohr is human, arguing with conviction for the values he himself believes. He is not exaggerated into a monster to make Sophie look angelic. The drama of the movie is the clash of ideas between the two. This is reflected again in the Nazi show trial, where Hans and Sophie refuse to disavow their views or to betray any comrades.
