Another piece of casting for BBC Three’s Class has appeared online.

Set in contemporary London at the fictional Coal Hill School, the eight-part Doctor Who spin-off begins filming this month.

It was revealed last week that actor Greg Austin, best known for playing Gordon Selfridge in ITV’s Mr Selfridge, will play a character named Charlie in the show.

Today it’s also emerged that Nigel Betts (Boy Meets Girl) will be appearing in Class.

The Emmerdale actor will be reprising the role of Mr Armitage.

Betts previously played the Coal Hill School staff member in 2014’s ‘Into the Dalek’ and ‘The Caretaker’, followed by a voice-only cameo in ‘Dark Water’.

Class writer Patrick Ness has confirmed that official “announcements” are on the way very soon.

The official synopsis for Class reads: “Incredible dangers are breaking through the walls of time and space, and with darkness coming, London is unprotected. With all the action, heart and adrenalin of the best YA fiction (Buffy, Hunger Games), this is Coal Hill School and Doctor Who like you’ve never seen it before.”

Class will premiere later this year on BBC Three in the UK and on BBC America in the US.
