Warner Bros. is not holding back for the final Potter film. According to Variety.com they will "absolutely, hands-down, across-the-board" make a push for Deathly Hallows - Part 2 to be nominated for Best Picture:
"Studio is pulling out the stops to mount a best-picture campaign for the last installment of the 'Harry Potter' franchise, taking a page from the 'Lord of the Rings; playbook that New Line successfully employed to land the 2003 best picture Oscar for the trilogy's final installment, 'The Return of the King,' along with 10 other Oscars."
Despite nine previous nominations, no Potter film has ever won an Oscar. According to FirstShowing.net, it is likely Part 2 will receive nominations in score, visual effects and other technical categories.
