Star Wars 7 suffers another major leak as the first look of Luke Skywalker has been revealed. The Jedi Master's look has been a well kept secret by JJ Abrams and Disney/Lucas Films.

The trailers of the space thriller have revealed the first look of Han Solo, Chewbacca, Kylo Ren and C-3PO along with other important characters.

However, to the disappointment of fans the director and producers only allowed fans to listen to Luke's voice while he explained the power of the Force in the previous teaser, keeping his looks in the upcoming movie hidden.

Star Wars 7 News posted a behind-the-scenes shot of Mark Hamill in his full Jedi robe but the website later removed it on request.

Consequence of Sound, however, still has the image which can be viewed by clicking here.

In the image, Hamill's character appears to come from a 3D imaging session while wearing the flowing robes and the hood.

The highly anticipated space opera has been a victim of numerous plot and scene leaks ahead of its premiere scheduled in December 2015.

In July, the synopsis of the movie leaked on 4chan which revealed that the space odyssey will take place 30 years after the events of the Return Of The Jedi and the ruthless prince Kylo Ren, who is obsessed with power will frantically search for the lightsaber that tumbles out of space in the planet of Jakku.

In order to bring galactic peace, the runaway soldier Finn, an uncongenial scavenger Rey, and a hotshot pilot Poe will find their fates intertwined as they embark on a journey to find the most powerful warrior Luke, son of Darth Vader in the galaxy.

Star Wars 7 is the first of a new trilogy starring original cast members Harrison Ford, Carrie Fisher, Mark Hamill, Anthony Daniels, Peter Mayhew and Kenny Baker alongside Andy Serkis, Max von Sydow, Oscar Isaac, Adam Driver and Domhnall Gleeson, plus relative newcomers and British actors John Boyega and Daisy Ridley.
