Plot and character details for the movie (will it focus on young Han Solo? Young Leia?) are being kept hidden deep in an R2 unit. Insiders say that reading and testing for the movie occurred in the U.K. in December and has now moved stateside.

At this stage, Lucasfilm has two Star Wars stand-alones in development, one with Edwards, the filmmaker behind last year's Godzilla movie, and Josh Trank. Only the Edwards one has a release date: Dec. 16, 2016.

Edwards' project is currently seeking writers after Garry Whitta completed a first draft and left the project.

In the aftermath, rumors surfaced that Simon Kinberg, who is already co-writing the Trank stand-alone with Lawrence Kasdan, would take over writing during. Sources, however, say that while Kinberg is creatively involved in Star Wars in an overall manner, there are no plans for him to take over. Kinberg is additionally crafting the X-Men universe, writing the X-Men: Apocalypse script for Fox and overseeing the upcoming Fantastic Four reshoots for which he did the rewrites.

Disney had no comment on the testing nor did the actress' reps.
