'Star Wars Episode 7' Cast Joined by British Actress Christina Chong

The Star Wars Episode 7 cast has a new addition with actress Christina Chong.

Her previous work includes spots on Doctor Who and 24: Live Another Day. Chong's role in the film has not yet been revealed. She will also star as the female lead in the upcoming Halo: Nightfall live-action digital feature that is being directed by Sergio Mimica-Gezzan of Falling Skies.

Chong will join Star Wars returning vets including Mark Hamill, Harrison Ford and Carrie Fisher.

Other new additions to the film's cast include newcomers Crystal Clarke, Pip Anderson and Carrie Fisher's daughter Billie Lourd.

Clake and Anderson were discovered during an open casting call held last year by Lucasfilm in 11 cities across the U.S. and U.K. Clarke and Anderson were chosen from 30,000 actors and actresses.

Lucasfilm president Kathleen Kennedy commented on them joining the cast in a recent statement.

"The Star Wars universe has always been about discovering and nurturing young talent and in casting Episode VII we wanted to remain absolutely faithful to this tradition," she said. "We are delighted that so many travelled to see us at the open casting calls and that we have been able to make Crystal and Pip a part of the film."

Lourd was chosen by director J.J. Abrams due to her resemblance of her mother. Lourd will even have scenes in the film where she will sport the classic Leia-style buns, according to a report from the Daily Mail.

Lourd is the daughter of Fisher and entertainment agent Bryan Lourd.

Star Wars Episode 7 opens in theaters on Dec.15, 2015.
