There are heaps of screecaps available from the Five Armies trailer now, but if you’re keen on the highest resolution available you’ll want these ones.
Warner Bros. supplied our friends at Herr-der-ringe-film.de 11 “official” high-resolution screencaps from the trailer… and they look super-crisp. We’ve reproduced four directly below; head to HDRE to grab the lot of them.
One thing I noted is just how many of these images directly feature, or involve, Thorin. Again this raises a concern that Bilbo’s heroism and audacity could become subsidiary to the Thorin story-arc.
