Based on the information herein below, we know alot of what happens in The Force Awakens
Returning to reprise their roles in "Star Wars:Episode VIII' is Golden Globe Award nominee Oscar Isaac as Poe Dameron; Daisy Ridley as Rey; Black Reel Awards nominee John Boyega as Finn; Academy Award nominee Harrison Ford as Han Solo; two-time Primetime Emmy Award nominee Carrie Fisher as Leia; and BAFTA Award winner Mark Hamill as Luke SkyWalker. Also joining the cast of"Star Wars: Episode VIII'is Academy Award winner Benicia Del Toro, who will play the role of a villain.
It's kind of a bummer that we will have to wait an extra seven months for the next installment of the main saga, but I did like the December release of TFA. Christmas and Star Wars at the same time make me happy.
There's a key Luke monologue here, full of spoilers if true. Seems rather long and repetitious, could be retold from memory or otherwise pieced together. Could all be fan fiction based on a leaked set picture.
The source of that rumor is ripped a new one in the article comments, being called SuperShadow 2.0.
That being said, there definitely is some kind of "I am your father" twist moment coming up the pipeline, everything points to that direction. If you want my guess, this whole beating around the bush about Rey's parentage is one big red herring. The reveal is the un-reveal: she is Luke's daughter. The real twist is that Kylo Ren is Luke's offspring as well, making him and Rey siblings, not cousins. Han and Leia were simply Ben's foster parents.
While some online are already speculating this is rather early and could signify the film being moved up, I would point out that his schedule could have been set back when they were still expecting the film to release in May.
TFA established that Luke tried rebuilding the Jedi Order but failed, so he's the only "full Jedi" remaining. He's not the only one left with strong force powers, but "technically" the last "trained" Jedi.
