Okay, so after seeing a picture on Facebook about this (picture above), I thought, "Hey, let's make a petition," and over 200 other fans agreed.

The advantages to a Luke movie?
Well, after Disney threw out the entire Expanded Universe, there is room for a new EU. Disney + Expanded = Dispanded. The Dis-panded Universe! The planned spinoff films will most likely contribute to the Dis-panded Universe, as the new-canon books have done so far. But there is still so much to be discovered! What happened to Luke after Return of the Jedi? What did his Jedi Academy look like? Who were some of the students? Was the system at all similar to the Old Jedi Order?
This can be written in books, sure, but not only would that make things confusing for people who do not grasp the concept of the EU, but would also seem like a complete rip-off from the Jedi Academy trilogy and "I, Jedi" (unless they find a way around this, which I doubt. *cough coughForceAwakenscough cough*), if put into book form, that is. Not even books can explain the difference that well, unless the author goes more biography mode or whatever. You know. Something like C. S. Lewis did with The Chronicles of Narnia. As awesome as it would be, Star Wars simply isn't Narnia. A book like this would never make it, not after the afore-mentioned books. We also need to see the bond between Luke and Leia fully blossom, now that they're brother and sister and (hopefully) not trying to make babies together. We saw their bond tighten in the Expanded Universe, sure, but not really at a deep level. To be honest, they were only closest after Anakin Solo died. Plus, it would be interesting to see Jedi in-training on the big-screen (those few glimpses in the Clone Wars series and Attack of the Clones was complete bullsh*t), and how exactly Luke kept things under control. Also, maybe we'd even see a few Jedi build lightsabers! Besides, Sebastian Stan looks EXACTLY like Mark Hamill did back in the 80's!

Just think it through!!!
