All the Cornley Polytechnic Drama Society wants to do is put on its latest show, a 1920s country-house murder mystery in the Agatha Christie vein – but everything conspires against this hilariously beleaguered amateur dramatics troupe.

Cast members forget their lines or are knocked out cold, music cues are muddled, the doors stick, and, piece by piece, the entire set collapses around them – even as the cast try desperately to keep the show going. Their wrongdoings will have you crying with laughter.

Check-in at Torquay’s most notorious hotel has been extended a final time at the Apollo Theatre. Adapted by John Cleese himself from the sitcom episodes “The Hotel Inspector”, “Communication Problems”, and “The Germans”, you can enjoy three uproarious storylines woven together in one show – all the more scope for uproariously chaotic farce!

Hotelier Basil, his wife and co-manager Sybil, Spanish waiter Manuel, and long-suffering chambermaid Polly are all present and correct. Don’t miss out before the hotel’s doors are locked for good on 13 September.

Max Bialystock and Leo Bloom are back in the West End transfer of the Menier Chocolate Factory production of Mel Brooks’s musical based on his 1967 cult classic, directed by Tony winner Patrick Marber. A get-rich-quick scheme contrived by two theatre producers proves to be more than either bargained for when a sure-fire flop becomes a hit, much to their consternation.

Andy Nyman (Hello, Dolly!) and Marc Antolin (I Wish You Well) reprise their roles as Bialystock and Bloom, with Joanna Woodward (The Time Traveller's Wife) as Ulla. The classic numbers include “I Wanna Be a Producer”, “Keep it Gay”, “The King of Broadway”, and, of course, “Springtime for Hitler”. Talk about bad taste!

Created by South Park’s Trey Parker and Matt Stone and composer Robert Lopez (Frozen, Avenue Q), The Book of Mormon is a rip-roaring satire that takes no prisoners and has been entertaining audiences for over a decade.

The musical follows two naïve and mismatched Mormon missionaries posted to a remote village in Uganda. It pokes fun at everyone, including the Mormons whose only knowledge of Africa comes from The Lion King, but it also shows a sweet friendship developing. The Book of Mormon is a madcap comedy with heart.

A new favourite musical comedy has docked at the Criterion Theatre and received the Olivier Award for Best Comedy or Entertainment. We all know the story of the ill-fated Titanic and the 1997 James Cameron film remains a fixture, but what if that wasn’t the whole story? What if Celine Dion, legendary singer of the film’s theme tune “My Heart Will Go On”, can explain what really happened?

Featuring all of Dion’s greatest hits, including “You and I”, “If You Asked Me To”, and “All By Myself”, Titanique is a campy, madcap joy that will send you overboard with laughter!

Is it a comedy or a horror show? Perhaps a bit of both for aspiring writer Andy, who is thrown in the deep end when she becomes junior assistant to fearsome fashion magazine editor Miranda Priestly. Miranda’s demands are outrageous and senior assistant Emily is fiercely competitive. Will she be able to stay afloat or be thrown out without a reference?

With a score by Elton John and plenty of fabulous fashion on display, the show stars Ugly Betty’s Vanessa Williams as Miranda and features all most famous sequences from the beloved film. That’s all!

There are two fantastic productions of Shakespeare’s colourful comedy of mistaken identity and gender fluidity to choose from. First up is Robin Belfield’s staging at Shakespeare’s Globe, which is set in the middle of a festival (perfect for the play’s carnival-esque qualities) but not everyone wants to join in with the revels.

How will the shipwrecked Viola find her way in this unfamiliar land, especially when she get stuck in the middle of an unusual love triangle? It’s Shakespeare, so things have a way of working out when you least expect them to…

Over the festive period, Prasanna Puwanarajah’s garlanded Royal Shakespeare Company interpretation of the comedy arrives at the Barbican. The cast includes Samuel West (All Creatures Great and Small, The Writer) as humourless steward Malvolio and Freema Agyeman (Doctor Who, Jamie Lloyd’s Romeo and Juliet) as the bereaved countess Olivia.

The play is set at midsummer but is named after the festival that takes place on 6 January, a day on which anything goes… The production promises to be “a bittersweet freewheeling miracle of farce, longing, love and life”.

Jonathan Lynn and Antony Jay’s political sitcom first aired in 1980, starring Paul Eddington and Nigel Hawthorne. Lynn and Jay adapted the series for the stage in 2010, playing first in Chichester and then the West End. The convoluted logic of Westminster politics will never not be relevant and utterly absurd.

The latest continuation, I’m Sorry, Prime Minster, stars Griff Rhys Jones (Not the Nine O’Clock News) as former prime minister Jim Hacker. Now retired at Hacker College, Oxford, Hacker finds himself in a fix when he’s cancelled by the college committee. Fortunately, Sir Humphrey Appleby (Clive Francis) is on hand with his talent for Machiavellian scheming.
