HARRY POTTER AND THE DEATHLY HALLOWS: PART I (PG-13): The first of the two-film adaptation of J.K. Rowling's final novel about the adventures of the boy wizard, who is now well into adolescence and facing off against the evil Voldemort. Director David Yates is almost certain to end this one with a cliffhanger: You'll have to wait until next summer to see how the story turns out.
