Earlier this week, an unidentified source revealed that Harrison Ford, Mark Hamill, and Carrie Fisher are "upbeat" about returning for Star Wars: Episode VII. Carrie Fisher recently went on the record, stating she would accept an offer to return as Princess Leia.
"Yes. Sure. Wouldn't you?"
It would make sense to bring Princess Leia back, along with Harrison Ford's Han Solo and Mark Hamill's Luke Skywalker, since the sequel takes place after Star Wars: Episode VI - Return of the Jedi. What isn't known yet is how long of a time gap there will be between Star Wars: Episode VI - Return of the Jedi and Star Wars: Episode VII.
There has been no shortage of speculation swirling around this project, with directors such as Matthew Vaughn and Colin Trevorrow reportedly circling the sequel. It also isn't known yet who will be writing the screenplay.
