This via Ain’t It Cool and elsewhere:
Looks like more test footage. I would question the provenance, but the style does like authentically Blomkampian (Neill Blomkamp being the director attached to the Halo movie; and yes, I am the first person to ever use that word). And those are some expensive effects shots, and the hardware looks right — there’s some Warthog action, and a quick Banshee flyby.
Interesting: the idea seems to be to shoot cartoony sci-fi action in an ultra-gritty, almost documentary style. I’m a sucker fanboy, I know, but it’s kinda workin’ for me. Someone really ought to fund this movie.
