It's the ship that made the Kessel Run in less than 12 parsecs, and now, according to a new rumor, the Millennium Falcon may be returning for J.J. Abrams' Star Wars: Episode VII.

Latino-Review reports that interiors of the Millennium Falcon have been completed at Pinewood Studios in London, where an estimated 90 percent of the film's production will take place. (The other 10 percent is expected to shoot in Los Angeles.)

This is by no means proof that the Millennium Falcon is in Episode VII, but with LR now backing the rumor as well, it certainly seems more likely than it did a few days ago.
