"Star Wars Episode VII" adds new member to its cast ensemble. Miltos Yerolemou who plays swordsman Syrio Forel on HBO's hit "Game of Thrones" is tapped to play an undisclosed character in the hotly-anticipated film directed by J.J. Abrams.

Set approximately thirty years after Return of the Jedi and the demise of Darth Vader, the plot centers around a trio of young leads, along with characters from the previous installments. Harrison Ford, Carrie Fisher and Mark Hamill return as Han Solo, Princess Leia and Luke Skywalker respectively.

The film will hit U.S. theaters December 18, 2015. It has resumed production after a brief break following Ford's on-set injury. John Boyega, Adam Driver, Lupita Nyong'o, Gwendoline Christie, Andy Serkis and Daisy Ridley are among the cast members.
