Though the word is overused these days, "epic" is the only one we can think of to describe the brand-new trailer for 'Harry Potter and the Deathly Hallows Part I.'

The second trailer, released today, reveals a much darker wizarding world. As the heart-pounding music swells, we see Harry and his friends battle the Dark Lord, show their best "emotional acting" faces and deal with some pretty heavy stuff. Watch it after the jump.
