Well, we didn’t have long to wait for the Guardians of Middle-earth trailer. A whole day and a half!
You can watch the trailer on YouTube:
They haven’t given us any details of who the combatants are (and I’m too impatient to wait a day or two), but Gandalf, Legolas, Gollum, The Witch-king, and Sauron are obvious.

this looks awesome. Just kinda wondering why ‘Thrain’ has Thor’s Hammer…..?
Yeah, at one point it even returns to his hand magically. Wha?
exactly! lol love it
WOW! Awesome screenshots!! Thanks you for posting this!
I am very curious as to the name of Thrains Hammer lol. It looks like a make-shift version of Mjolnir, Thor’s hammer. It lacks the strap but it returns to his hand after being thrown!
That it does. Maybe Gandalf added an extra spell to it or something. Sure, that totally explains it.
