As previously announced Star Wars: Episode IX started filming today and J.J. Abrams Tweeted a Behind-The-Scenes Photo of what looks to be a camera pointed through a cockpit of a Ship and in the background you can see a out of focus Finn.
Here is his Tweet:
"Bittersweet starting this next chapter without Carrie, but thanks to an extraordinary cast and crew, we are ready to go. Grateful for @rianjohnson and special thanks to George Lucas for creating this incredible world and beginning a story of which we are lucky to be a part. #IX"
