A searing debut from youngster Thomas Horn as a small boy trying to make sense of the death of his father on 9/11 distinguishes this multi-layered drama from British director Stephen Daldry. Horn plays Oskar Schell, a youngster with just a hint of autism, who worships his indulgent father (Tom Hanks). When dad dies during the World Trader Center attack, Oskar sets off on a mission to discover what lock can be opened by a key he finds hidden in a vase in his father's closet. Poignant and touching, it is - most of all - a glowing celebration of the bonds between father and son. Sandra Bullock and an Oscar- nominated Max Von Sydow co-star.
