Meet the cast of Doctor Who's new spinoff - the BBC Three teen drama Class.
Greg Austin, Fady Elsayed, Sophie Hopkins and Vivian Oparah are the young stars heading up the series from YA author Patrick Ness.
Katherine Kelly - of Coronation Street, Happy Valley and The Night Manager - is also on board, cast as "a teacher and powerful new presence" at Coal Hill School.
Coal Hill first appeared in Doctor Who's first ever episode in 1963 - with Class set to follow its students as they battle intergalactic threats.
The teens will have to navigate a life of friends, parents, school work, sex, sorrow - and possibly the end of existence.
An official synopsis for the series reads: "What if your planet was massacred and you were the sole survivor? What if a legendary figure out of space and time found you a place to hide?
"But what if the things that want to kill you have tracked you down? And worst of all, what if you haven't studied for your A-Levels…?
"Coal Hill School has been a part of the Doctor Who universe since the very beginning, but that has come at a price. All the time travelling over the years has caused the very walls of space and time to become thin.
"There's something pressing in on the other side, something waiting for its chance to kill everyone and everything, to bring us all into Shadow."
...and if all that hasn't got you hyped for Class, Doctor Who showrunner Steven Moffat has only gone and billed the series as "a British Buffy."
"Coal Hill School has been part of Doctor Who since the very first shoot in 1963, but this new show is anything but history," Moffat said.
"Class is dark and sexy and right now. I've always wondered if there could be a British Buffy - it's taken the brilliant Patrick Ness to figure out how to make it happen."
Class starts filming today (Monday, April 4) and will premiere on BBC Three later this year.
