No, ignore the date on the calendar. This story is actually legit.
From the official press release:
APRIL 1, MILWAUKIE, OR–It’s no April Fools’ prank! Dark Horse is honored to announce a dream project: working with J.W. Rinzler, executive editor at LucasBooks, and artist Mike Mayhew (Avengers) to adapt the rough-draft original screenplay which spawned the biggest franchise in film history!
Three years before his 1977 film, George Lucas put down on paper his first story set in a galaxy far, far away—a tale of fantastic adventures, daring escapes, “lazer swords,” romance, and monsters. A story of Jedi Annikin Starkiller and General Luke Skywalker, an alien named Han Solo, and evil Sith Knights. The screenplay was titled The Star Wars!
“I’m not sure where I first read about The Star Wars—it was years and years ago—but the idea of Luke Skywalker being an older Jedi General, and Han Solo being a six-foot-tall lizard, turned my Star Wars fan brain on its side,” said longtime Star Wars editor Randy Stradley. “I always assumed this would be one of those stories that would be ‘lost to history,’ so getting to work on bringing it to life is kinda like a dream come true.”
“While researching in the Lucasfilm Archives I’ve found many treasures—but one which truly astounded me was George’s rough draft for The Star Wars. His first complete imaginings were hallucinating to read—mind blowing,” said writer J.W. Rinzler. “While working with George on another book project, I once asked if we could adapt his rough draft. He was hesitant. Years later, with Dark Horse’s invaluable help, we showed him a few drawn and colored pages of what it might look like. He gave us the okay.”
And here's some sample art from the comic:
Those familiar with Ralph McQuarrie's concept art for the first movie will notice some familiar imagery.
I'm not much a comic buyer myself, but I'm seriously considering getting this.
