Big School (BBC One, Friday, August 16, 9pm)
When he’s not swimming for charity, scoping out variety acts on Britain’s Got Talent, or writing children’s books, David Walliams is a brilliant comedy actor.
He makes a welcome return to our screens in this new six-part sitcom, which, just like the Jack Whitehall vehicle Bad Education, is set in and around a dysfunctional staff room.
And, also like Bad Education, there is a story of unrequited love between two of the teachers at the centre. Walliams plays 40-something deputy head of chemistry Mr Church, who is about to resign from Greybridge following a particularly dramatic experiment with liquid nitrogen and 1000 ping pong balls.
But the arrival of French teacher Miss Postern (Catherine Tate) changes his mind.
However, Mr Church faces competition from lothario PE teacher Mr Gunn (Philip Glenister) who makes no secret of wanting to “plough” the new member of staff, prompting Mr Church to offer her a lift home.
Look out for Veteran Rising Damp actress Francis de la Tour as unconventional headteacher Ms Baron, who regards confiscating the kids’ alcohol as a perk of the job.
