**Update Photos and footage from the event now live here***

I may be pre-empting things but this could well go down as one of the all-time great publicity stunts! This evening, Anthony Daniels who played C-3PO in all six Star Wars movies, will press the button at 8pm converting London’s iconic BT Tower into a giant lightsaber. The stunt is being carried out to celebrate the launch of the Star Wars Blu-ray box set which came out on Monday (order your copy here).

The image below comes from Pocket-Lint and is a photoshopped mock-up to show what it may look like. I hope it does look something like this as it will look spectacular and I also hope planes have been warned flying overhead!

Either way, massive congrats to Substance, PremierPR and to Twentieth Century Fox Home Entertainment for making this happen and massive respect to British Telecom for letting it happen! If you’re in London tonight, look to the skies! Full press-release below.

We’ve been going Star Wars crazy all this week to celebrate the Blu-ray box set launch. Click here to see our rather extensive coverage and features.

LONDON FEELS THE FORCE AS STAR WARS®

BLU-RAY LIGHTS UP THE CAPITAL TO CREATE THE WORLD’S LARGEST LIGHTSABER

 LONDON, UK. (September 12, 2011) – As the UK becomes the first country in the world to release STAR WARS: THE COMPLETE SAGA on Blu-ray, London will feel the Force like never before as droids, Stormtroopers, Jedi and the Sith invade the city in a week-long Star Wars spectacular culminating in the galactic transformation of the BT Tower into the World’s Largest Lightsaber™.

The week commenced with a rude awakening from the Dark Side, as Darth Vader and a sinister fleet of Stormtroopers took to the streets in an Imperial March that will sent shivers down the spines of Londoners.  The march began at St. James’ Park where they joined Changing of the Guards activities, before proceeding to HMV on Oxford Street to meet shoppers as they queued to get their hands on the highly anticipated Blu-ray release.

Star Wars legend Anthony Daniels (C-3PO in all six episodes) will provide a lighter touch on Tuesday 13 September as he meets fans at the grand opening of the HMV at the new Westfield Shopping Centre in Stratford, signing copies of STAR WARS: THE COMPLETE SAGA on Blu-ray.  The loveable droid was central to all six smash hit movies and Daniels’ portrayal makes him a favourite with many Star Wars fans.

On Thursday 15 September, from inside the exclusive star-studded launch party at the top of the BT Tower, Daniels will press a button lighting up the London skyline for one night only as it morphs into a Jedi Knight’s elegant weapon of choice, projecting a giant ‘blue ray’ of light from the top of the tower.

In the words of Darth Vader himself, “This will be a day long remembered” by Star Wars fans in the UK and across the world.
