Despite rumors that it would wait until May 4 (also known as "Star Wars" Day) to reveal the cast of the upcoming J.J. Abrams entry in the classic science fiction series, Disney announced the key actors of the next "Star Wars" installment on Tuesday.

Actors John Boyega, Daisy Ridley, Adam Driver, Oscar Isaac, Andy Serkis, Domhnall Gleeson, and Max von Sydow will join the original stars of the saga, Harrison Ford, Carrie Fisher, Mark Hamill, Anthony Daniels, Peter Mayhew, and Kenny Baker in the new film.

There are a few familiar faces and a few relatively unknown players among the newcomers. Some readers may recognize Adam Driver as that guy from the HBO series "Girls" and the Swedish actor Max von Sydow from his decades-long career that included turns as a Bond villain and a part in David Lynch's adaptation of "Dune." But it might be harder to recognize Andy Serkis on sight, although many will recall some of his performances -- as Gollum in the "Lord of the Rings" films and as the titular giant gorilla in the 2005 "King Kong." And, of course, the old gang is back together -- although, no sign of Lando Calrissian.

The films is set to start shooting "in a couple of weeks," according to a statement from Abrams released with the cast list.
