Teenage Mutant Ninja Turtles movie remake billboards...

What's Summer without a Hollywood remake, as those heroes in a half shell, the Teenage Mutant Ninja Turtles get a 2014 big screen reboot for a new generation.

Springing out of the New York City sewers the humanoid teenage turtles named after infamous Renaissance artists, 'Raphael', 'Leonardo', 'Michelangelo' and 'Donatello', are back to battle evil with their ninja skills.

Created in comic book form by Kevin Eastman and Peter Laird, the kick-ass, pizza-eating amphibian quartet and their mutated rat sensei 'Splinter' have enjoyed many on screen incarnations in cartoons and live-action outings, including their big screen debut way back in 1990.

Now they've returned with a new look (their turtle faces causing some controversy amongst fans) in their familiar different colour masks to try and dominate the hearts of cinema goers everywhere again (just like they are dominating the skies of L.A. at the moment).

Once again they'll face their arch-foe and martial arts expert, 'Shredder', and his Foot Clan, plus this time out their reporter friend 'April O'Neil' is played by Megan Fox (well the new TMNT film is produced by Michael Bay after all).

With superhero movies still all the rage, this outdoor ad campaign which focuses on the Turtles iconic masks is a clever move, especially when you add a bit of technological magic into the mix to spice things up.

Along with all the giant-sized billboards and deluge of other out-of-home ad creatives, this masked billboard along L.A.'s Sunset Strip is extra special, as by day it's orange with blue eyes and by night, to create some intrigue for passersby, the mask turns red and the eyes become green. Those clever ninjas are masters of disguise (aside from being giant green amphibian teenagers, that is).

And here's how it happens, courtesy of being back lit by some electroluminescent Light Tape, which goes on beneath the special vinyl billboard creative to create the cool metamorphosis effect, and add a touch of drama to the skies of L.A.

And if you like this concept, you should also check out this special electroluminescent billboard for The Amazing Spider-man 2 where the villain 'Electro' appeared to battle the web-slinger when the sun went down.

For the uninitiated, Raphael wears the red mask, Leonardo the blue mask, Michelangelo the orange mask and Donatello the purple mask, each with their own preferred fighting weapons, from swords to sais, nunchucks to bo staffs.

The super-sized vertical billboards with all four Turtles in their heroic poses were spied towering over Hollywood at Sunset & Vine, with the rest of the billboard creatives snapped around the streets of L.A. from July 15 to July 27, 2014.

Only time will tell if this latest cinematic incarnation can capture the nostalgia of the 90's and set the stage for a whole new rebooted film franchise which pleases existing and new fans alike.

Of special note is the trio of giant-sized billboards on the side of the Figueroa Hotel in Downtown L.A., which cleverly manages to fit all four Ninja Turtles onto only three towers, creating a fantastic spectacle.

At the end of the day, there's only one thing to be said about this movie - Cowabunga dudes!

Suddenly Daily Billboard has a craving for pizza.
