The image above of Voldemort, Bellatrix, and Death Eaters comes from Entertainment Weekly, and is likely their reaction to Harry appearing in the forest (which we saw during the opening of the teaser trailer). They also have an image of Neville Longbottom with The Sword of Gryffindor during The Battle of Hogwarts, and a shot of Harry in a Gringott’s vault.
Warner Bros. also uploaded 2 new images onto their Facebook page, including the image above of the trio in distress (well Harry and Hermione are anyway, Ron appears to be fine). The other image features Draco Malfoy, Goyle and Blaise in The Room of Requirement, which you can see here.
In the film, once again directed by David Yates, Harry, Ron, and Hermione return to Hogwarts after months on the run in the wilderness with the aim of finding, and destroying, Voldemorts final horcruxes. Voldemort finds out about their mission and the biggest battle of their lives begins as the Dark Lord and his Death Eaters descend upon Hogwarts.
Producer David Heyman has said The Battle of Hogwarts will last 30 minutes long and they have beefed up the final Harry vs. Voldemort battle, so we can expect a finale of epic proportions.
Harry Potter and the Deathly Hallows: Part 2 will be released July 15th, and we can probably expect a trailer to be released sometime soon.
