Pacific Rim movie billboards...

There's lots of huge Summer blockbusters this year, filled to the brim with superheroes, fast cars, zombies and starships, but Pacific Rim literally has the 'biggest' stars this season.

When a rift opens at the bottom of the Pacific Ocean letting in destructive gigantic beasts from an alternate dimension, it's up to humanity to build a better monster to safeguard mankind.

To combat these 'Kaiju' monsters, massive robotic machines called 'Jaegers' are constructed, which are piloted by two people whose minds are linked together to control the giant suits.

As you can see, this Summer L.A. has been invaded by these gigantic mech suits and their Godzilla-like adversaries.

And it's a good thing that these billboard creatives do feature monsters as well as huge robots, otherwise they run the risk of looking a lot like previous Transformers movie billboard ad campaigns, which we've all seen before.

It's only fitting that this blockbuster movie has its own super-sized billboards along Beverly Boulevard, Sunset Boulevard and towering over Sunset & Vine in Hollywood. 

The special extension billboard was spied along La Brea Avenue, whilst the other landscape creatives were spotted along Sunset Boulevard, Cahuenga Boulevard and Melrose Avenue (and more besides) from June 8 though to June 21, 2013.

Only time will tell whether Guillermo del Toro's Pacific Rim will it be a monster smash, or monstrous mess?
