Before "Schindler's List" came Grede's engrossing portrait of a man who risked everything to protect others from ignominious slaughter. In the end, Wallenberg saved thousands, but was himself accorded a different fate. Skarsgard portrays this little-known hero with dignity and gravitas, while Katharina Thalbach delivers a fine performance as one of the haunted souls he protects: Marja, a witness to the slaughter of her own children. Grede does not shy away from depicting Nazi abominations, and the suspense he builds around the discovery of a group of survivors, and the march of the Russian army on Budapest, is unnerving. "Wallenberg" is an unblinking tribute to a remarkable man of action.
