The production went on a two-week hiatus earlier this month due to an injury star Harrison Ford sustained in June. Ford was sidelined after breaking his left leg on the London set June 12 and later underwent surgery.

Ford showing up — and appearing to be back in good health — at Monday's The Expendables 3 premiere in Hollywood had Star Wars observers speculating that he is ready to return to a galaxy far, far away.

Sources could not confirm if Ford was flying back to London to join the production.

Episode VII is filming at the U.K's Pinewood Studios and also stars familiar faces Carrie Fisher, Mark Hamill, Anthony Daniels, Peter Mayhew and Kenny Baker, as well as series newcomers John Boyega, Daisy Ridley, Adam Driver, Oscar Isaac, Andy Serkis, Domhnall Gleeson, and Max von Sydow.

It's slated for a Dec. 18, 2015, release.
