Halo - Warthog Cloned, Red Vs Blue DVD-ed
Thanks to Eurogamer for their news item highlighting the similarities between Peugeot's new Hoggar concept car and Halo's Warthog buggy. The article's tongue-in-cheek disclaimer argues: "We feel sure that any similarity is entirely coincidental", and the likeness was originally brought to light by Halo machinima crew Red Vs. Blue, who have also just released the Season 1 DVD for their much-lauded machinima series, including "all episodes, PSAs, extra videos, outtakes, easter eggs and a directors commentary" - the basic episodes are also still freely downloadable in DivX/Quicktime formats for interested parties.
From the article on the Warthog: actually reminds this writer of the buggy from the start of Star Trek: Nemesis (which was even more clearly a Warthog rip-off!)
Star Trek Nemesis probably had those buggies built long before anyone on the team had played Halo. Nemesis released at the end of 2002, Halo released at the end of 2001. I would bet that Star Trek was filming before Halo was released.
MORTAR COMBAT!
