Simon Kinberg has opened up to EW about the work he has done on Star Wars. Kinberg, Michael Arndt, and Lawrence Kasdan spent a week putting the sequel trilogy and Anthology film outlines together. Kinberg tells EW:

Like a TV writers room, we spent a week with a whiteboard and some pens and were in a conference room all day talking about [movies] VII, VIII, and IX.But it’s a whiteboard covered in our notes. We had a sense of what we each wanted to write. It was the most magical time because we were writing Star Wars movies. Then we would go back to the inn at Skywalker and have dinner and drink a little bit and Larry would tell me and Michael stories about the moment in his life where he wrote Raiders of the Lost Ark, The Empire Strikes Back, The Big Chill, Body Heat all in the span of, I think, five years. So we just had this crazy, magical time together.

Kinberg then elaborates on his involvement as the process continued:

I’m like a friend of the court. I consult on the movies. I worked on VII: helped break the story, read scripts, drafts at certain points, and gave my thoughts whatever they were worth.

You also can’t leave out that Simon Kinberg went on to write some of the most pivotal episodes in Star Wars Rebels and plotted that show out with Dave Filoni and Greg Weisman. When you look at everything together you really see that Kinberg is a huge part of the creative team for this era of Star Wars.
