One was in Russell Crowe's Robin Hood, one played Bill Weasley in Harry Potter and another stars in Girls.
Meet the new instalment of Star Wars stars who will join original actors Harrison Ford, Mark Hamill and Carrie Fisher in Star Wars: Episode VII.
Driver is a breakout star best known for playing Hannah's aloof lover Adam in HBO series Girls, but the 30-year-old has also been in a slate of films including the Coen brothers' Inside Llewyn Davis (2013) and Frances Ha (2012).
He also played Washington war-room telegraph officer Samuel Beckwith in 2012 film Lincoln, and in January was added to the cast of Martin Scorsese's film Silence.
For weeks rumours have swirled that Driver has been cast as a Darth Vader-like villain.
Isaac received plenty of attention for his acclaimed performance as a struggling folk singer in the lead role of Inside Llewyn Davis.
It came after the 35-year-old had settled for supporting roles in other Hollywood films such as Russell Crowe's Robin Hood and Drive.
He also played Jose Ramos-Horta in 2009's Balibo opposite Anthony LaPaglia, and features in The Bourne Legacy (2012) and Sucker Punch (2011).
Boyega is a largely unknown young British actor known for the 2011 science fiction monster movie Attack the Block, in which a teenage gang defends their south-London block from aliens.
The 22-year-old has appeared in several British TV series, including Jeremy Piven's series Mr Selfridge.
Rumours suggest he may play a lead role, which would make him the first black lead in the Star Wars series - James Earl Jones did do the voice of Darth Vader, but at his own request wasn't credited in the original release of either Episodes IV or V.
Gleeson may be more recognisable than most of his fellow newbies, but Weasley brothers generally are.
The 30-year-old Irish actor played Bill Weasley in both parts of Harry Potter and the Deathly Hallows.
He is the son of actor Brendan Gleeson, who plays Alastor Moody in the series.
Gleeson is also known as the simpering bandit in the Coen brothers' True Grit (2010), played opposite Rachel McAdams in 2013's About Time and appeared in 2012's Anna Karenina.
He has also acted frequently on stage, earning a Tony nomination in 2006 for his performance in The Lieutenant of Inishmore.
Ridley is the least known, with no Wikipedia page and only a handful of British TV credits to her name.
Her first role came in 2013 on the BBC series Casualty, and she's appeared in an episode of Mr Selfridge and on Silent Witness.
Ridley's role in Star Wars has been described as "a young black or mixed-race woman who may be a descendant of Jedi Knight Ben Kenobi".
