David Walliams

From Please Sir! to Jack Whitehall's Bad Education, schools are a magnet for the sitcom gang.

The latest to answer the ringing of the bell is David Walliams, taking half-term break from teasing Simon Cowell to play lovestruck chemistry teacher Keith Church.

The object of the bumbling Keith's affections is la belle Miss Postern (Catherine Tate), the flame-haired new French teacher who doesn't actually know much French.

With Philip Glenister as a randy PE teacher, Frances de la Tour as a mean headteacher, Joanna Scanlan as a lesbian drama teacher and a scandalously under-used Daniel Rigby, the cast is top-notch - even if the jokes are a little old school.

New sitcoms on mainstream channels always stare directly into the jaws of darkness as purse-lipped audiences wait, arms crossed, to be entertained. Big School probably faces an even more hostile reception as it's co-written (with the Dawson Brothers) by David Walliams, who also stars. I bet there are a few people waiting to take him down a peg or two.

So please give Big School a chance. It doesn't ooze sophistication, in fact it's pretty silly. But it has a great cast and I heard myself laughing out loud in a few places. Walliams is secondary school deputy head of science Mr Church, a shy man with a terrible perm who's inexperienced with women and who listens to Phil Collins in his Austin Allegro. But he's transfixed by the new French teacher, comely Miss Postern (Catherine Tate). Big School turns out to be rather sweetly old-fashioned - in a good way.

David Walliams' new show is a masterclass in comedy

Hurrah! An old school sitcom: No wobbly cameras or vile language - just real characters and good jokes. David Walliams' new show is a masterclass in comedy.

The public disembowelling of The Wright Way will have put a few comic heavyweights on alert about upcoming projects, but David Walliams doesn't have too much to fear where his new sitcom Big School is concerned. It may be a little light on jokes, but it's transparently good-natured, agreeably old-fashioned and with an adult cast so attention-grabbing that the pupils occasionally feel a little incidental to proceedings.

Walliams is Mr Church, the sad-sack chemistry teacher who withdraws his proposed resignation when highly desirable maverick French teacher Miss Postern (Catherine Tate) arrives to shake up Greybridge secondary school. Frances de la Tour's withering headmistress, Daniel Rigby's clueless music tutor and Philip Glenister's non-PC PE teacher all grapple over scenes to steal and prise some good laughs out of the sometimes slight material.

It's no Grade-A student, but Big School isn't expulsion fodder either - a decent achievement with so few new sitcoms worthy of a pass these days.
