Peter Jackson's WETA studios, the amazing nerds they are, sent Bungie some awesome props from the now dead Halo movie.
"Yeah, the Halo movie's on a long, unpaid vacation, but that doesn't mean Peter Jackson's WETA special effects studio have been sitting on their collective asses. They've already made a bunch of weapons and props for the film, and with the project doing naught but gathering dust, they figured they may as well send some over to Bungie, let them have a go. Here, you can see the results."
Its things like these that make me cry at night when I think of how good a Halo movie could have been.
