Operation Chastity, the Halo fan-film, made a big and important step to realisation today with the unveiling of their custom made full size M12 ‘Warthog’ LRV today at the London Expo. The beast is built on the chassis of an old Land Rover by the talented guys from Custom Creations and certainly looks the part complete with internals and a mounting point for your gun of choice.

Hit the break for more details on Operation Chastity and some choice shot of the Warthog in full glory.

Taking a full year to put together, the completed warthog moves the fan-flick onto the next stage, which is due to start filming next March 2010 if everything goes to plan. By November 2010, Peter Cooper (pictured above) the Writer, Director and Producer of this epic undertaking, is hoping to enter post-production, which should last about 8 months. With a bit of luck, lots of blood and sweat and a bit of will power, we might start seeing the finished masterpiece sometime in the second half of 2011. To make things even better, according to Mr. Cooper himself, you may even be able to own a little piece of this Halo universe as the props, costumes and uniforms (including the 100 or so Spartan Marine outfits) will go on sale after the films release.

Now I don’t know about you but I’m absolutely stoked by the thought of a Halo film and having met Peter, I can assure you that the fan-flick is in safe hands. So if you want to support the film, get behind the crew and check out Operation Chastity and follow them on Twitter (@opchastity).
