Disney and Lucasfilm confirmed the latest instalment in the series would be set about 30 years after the events of Episode VI: Return of the Jedi.
It “will star a trio of new young leads along with some very familiar faces”, the press release added.
Star Wars: Episode VII, directed by JJ Abrams, will be released in cinemas on 18 December 2015.
The news of a return for “some very familiar faces” will fuel rumours that the stars of the original trilogy – Mark Hamill, Harrison Ford and Carrie Fisher – will appear in Episode VII.
Open auditions: According to the Hollywood reporter, Adam Driver is in final negotiations to play the main villain.
He is best known for his role in hit TV series Girls, but has also recently appeared in films including Lincoln and Inside Llewyn Davis.
Open auditions for two roles in the new films were held in the UK and Ireland last November.
They were a “street smart and strong” orphaned girl in her late teens and a “smart capable” man in his late teens or early 20s.
It is not known whether any of the actors eventually cast in the film were found through the open auditions.
Episode VII will be the fifth Star Wars movie to to be shot in the UK.
