Big School: character profiles
Character profiles for new BBC One comedy series, Big School.

Deputy Head of Science, Mr Church has been at Greybridge School for 15 years. Disillusioned with teaching, he is about to resign after a particularly dramatic experiment with liquid nitrogen and 1000 ping pong balls is met with apathy by his pupils.
However, the arrival of new French teacher Miss Postern changes everything - and Mr Church’s resignation letter goes in the bin. He’s socially awkward, but the presence of Miss Postern brings out the romance in his soul. Perhaps a lift home is the way to her heart? The course of true love never did run smooth – particularly in an Austin Maxi.

Greybridge School’s new French teacher Miss Postern has arrived to take up her post following the tragic death of her predecessor. She’s determined to make a difference in the classroom with new teaching methods – anyone for Vocab Tennis? Her guilty secret (revealed to Mr Church) is that she has never been to France. Sometimes she thinks, “To hell with it Sarah, jump on the ferry and go for the day!” As Mr Church says, she’s such a free spirit. She certainly enjoys having the attention of so many of the other teachers – “I can’t help it if every male member of staff and one female member of staff finds me attractive”.

PE teacher and would-be lothario Mr Gunn is also interested in the new French teacher - and most of the other female teachers in the school. The alpha male of the Greybridge staff room, which isn’t saying much, Mr Gunn lives in a world where Jeremy Clarkson is a revered philosopher and living with your mum despite being middle-aged is totally fine - “She does all the cooking, all the washing, all the cleaning. I’m living the dream.” Mr Gunn is determined to “plough” Miss Postern – probably on Friday night when his mum is at seniors’ zumba.

Greybridge’s no nonsense Head Teacher Ms Baron runs the school with a rod of iron and a kingsize cigarette. She sees both staff and pupils at Greybridge as hindrances to her life; she rarely leaves her office and never lets anyone sit on her newly re-upholstered chairs. Any alcohol confiscated from the pupils goes straight into the boot of her car as a perk of the job, and her attitude to drugs is not necessarily advocated by OFSTED. The staff seem to give her as much trouble as the pupils. “This is a new low for the school - and believe me there have been some quite startling lows.”

Geography teacher Mr Barber has been having a textbook nervous breakdown for the last two years. His wife’s left him, the bailiffs have taken the TV from his caravan and he’s desperate to negotiate himself some long-term paid sick leave. Despite it all, Mr Barber still wants to inspire his students with geography – “But Sir, I don’t want to be a geography teacher”, “Dare to dream!”
Mrs Klebb played by Joanna Scanlan
Mrs Klebb’s life revolves around teaching drama and spending time with her partner Frieda (Mr Gunn: “When it comes to lesbians the internet is very misleading”). Mrs Klebb directs radical adaptations of the classics but drama’s not only what she teaches, it’s also what she likes being a part of in the staff room - “I’m not earwigging, I’m just toasting some gluten free bread”. In fifteen years of theatre reviewing for the school magazine Mr Church hasn’t written anything remotely pleasant about her work.
Mr Martin played by Daniel Rigby
Music teacher Mr Martin likes to liven up his music classes with some of his own compositions - “Mozart? Yawnsville. No beat.” Being a teacher is really just a stepping stone to becoming a singer-songwriter like his musical soulmate ‘Eddie’ Sheeran. But his guitar playing is rudimentary, his lyrics are hamfisted and his musical knowledge isn’t as good as you’d expect.
Pat played by Julie T. Wallace
Mr Church’s loyal lab assistant Pat never speaks, but her actions make it quite clear that Mr Church is the only man for her - “You can stop rubbing that test tube now Pat…” - even if her love for him remains unrequited.
Mr Hubble played by James Greene
Elderly Head of Science Mr Hubble is frequently confused. As his superior, Mr Hubble is the one man standing between Mr Church and the position of department head. However, Mr Hubble’s not as sharp as he used to be and often walks into Mr Church’s class and starts taking the lesson as if they were his own, and occasionally mistakes Ms Baron’s office for the gents.
