According to a report in The Sun, Disney executives have picked a location in Kent, England to film battle scenes for Star Wars Episode 7. The location is reported to be a disused quarry in Greenhithe, which is near the Bluewater mall.
While this information is of course unconfirmed by Disney, it would not be surprising for Star Wars Episode 7 to at least partially film in England. Several scenes from previous Star Wars movies were filmed in the UK. Also, the disused quarry in question has reportedly been used as a Doctor Who filming location, so it must have an other worldly look.
Star Wars Episode 7 is due to be released in theaters sometime in 2015.
