Oscar-winning actress Lupita Nyong'o and Game Of Thrones star Gwendoline Christie have been added to the cast of the new Star Wars film.

Mexican-Kenyan Lupita has landed her role after drawing acclaim for her performance in 12 Years A Slave and landing an Academy Award earlier this year.

British actress Gwendoline has built up her profile after appearing as Brienne of Tarth in epic fantasy series Game Of Thrones and will soon be in The Hunger Games: Mockingjay - Part 2.

They join original members of the first Star Wars trilogy of movies Mark Hamill, Carrie Fisher and Harrison Ford in the cast for the eagerly anticipated Episode VII which began production last month.

Other figures who will be seen in the movie - being directed by JJ Abrams - include Daisy Ridley, Oscar Isaac, Andy Serkis and Domhnall Gleeson.

Kathleen Kennedy, the president of production company Lucasfilm, said: "I could not be more excited about Lupita and Gwendoline joining the cast of Episode VII. It's thrilling to see this extraordinarily talented ensemble taking shape."

Composer John Williams returns once again to create the score for the film, as he has done on all six of the Star Wars films. He won an Oscar for his work on the first of the movies.
