Jj Abrams' team building sessions for Star Wars Episode 7 appear to have given away the cast for the forthcoming sci-fi epic. Sources speaking with The Sun reveal that Abrams took his new cast and crew out to a swanky London eatery in a bid to get the team "gelling."

Attending the meal was Harrison Ford, who played Hans Solo in the original movies, Carrie Fisher, who played Princess Leia and Peter Mayhew, who played Chewbacca. Joining them around the table was 'Girls' star Adam Driver, who has been cast to play a villain, and Andy Serkis, whose role is yet to be determined.

"The cast are being flown out to various locations to film," said the insider, "Bosses want to capitalise on them all being in London by booking in aget-together . It was a top secret mission, nobody was allowed to let on they'd be meeting up."

The Hollywood Reporter's Borys Kit had previously tweeted that Isaac had been in negotiations for Star Wars Episode 7 but dropped out due to a scheduling conflict with a theater commitment. 

Star Wars Episode 7 is set for release in December 2015.
