Agatha Christie’s Murder On The Orient Express may be heading back to cinemas with an A-list cast, but Gold's TV version of the tale has signed up some pretty impressive stars, too.

The one-off comedy moves the action to a coach trip to Blackpool, where the OAP customers start to die under suspicious circumstances while the driver battles to find the killer and win over his tour guide colleague in the process.

Get to know the cast and characters of the dark comedy which is sure to tickle audiences and keep viewers guessing who the murderer is.

Terry – Johnny Vegas

Lead character Terry is the disillusioned driver who is struggling to find meaning in his life and whose only aim is to win over Gemma, who he is in love with. When Terry realises that his passengers are being bumped off, he springs into action to find out who is responsible while trying his best to keep the police at bay.

Comedian Johnny Vegas is known for his long-running role in holiday sitcom Benidorm, as well as classic comedy spin-off Still Open All Hours. He starred in the series Moone Boy and makes regular TV panel show appearances, but some viewers may remember him as the face of PG Tips with his puppet friend Monkey.

Gemma – Sian Gibson

As the owner of the coach tour company, Gemma is immensely proud of the service she provides giving guided tours of the North of England. Gemma teams up with Terry to get to the bottom of the mystery and ends up finding herself attracted to him.

The bus company specialises in literary tours, and David is the flamboyant, pretentious author whose books this particular trip is centred on.

David is played by Griff Rhys Jones, the star and co-creator of long-running sketch show Smith & Jones. He also wrote and starred in Not the Nine O’Clock News, and he had a successful stint as Fagin in a West End production of Oliver! from 2009 to 2011.

His film roles have included Stardust, Charlie and the Chocolate Factory, and The World’s End.

Moira – Nina Wadia and Laura – Kimberley Nixon

Prickly Moira is a real battleaxe whose difficult nature means that she has no friends. She is reliant on her badly-treated carer Laura, who puts up with all manner of temper tantrums from her charge.

Screen star Nina Wadia spent many years playing Zainab Masood in EastEnders, but is also known for her roles in sketch show Goodness Gracious Me, hospital drama Holby City, and revived sitcom Still Open All Hours.

Welsh actress Kimberley Nixon’s earliest role was in period drama Cranford, but it was university comedy Fresh Meat that made her a star. She went on to appear in sitcom Hebburn, crime thriller New Blood, and popular drama Ordinary Lies.

Doc – Nigel Havers

The doctor is a suave, debonair presence on the tour and the other passengers feel more than a little impressed that there is a medical man on board.

Nigel Havers’ extensive back catalogue of work has brought him national treasure status among his fans. He is known for films Chariots of Fire, A Passage to India and Empire of the Sun, a spell in Coronation Street, and roles in Downton Abbey, Little Britain and Benidorm.

Kevin – Kevin Eldon

Also on board is the doctor’s brother Kevin, who is reliant on Doc as he has lost his memory. Doc tells him it happened after a bump on the head – but is that the whole story?

Grace – Katy Cavanagh and George – Matthew Cottle

Married couple Grace and George are a cut above everyone else – or so she tells her husband. George finds the easiest way to deal with life is to do exactly as Grace tells him, but what trouble could this land him in?

Katy Cavanagh will be most recognisable as Coronation Street’s ditzy Julie Carp, while Matthew Cottle starred in 90s sitcom Game On and has been seen more recently in Citizen Khan.

Marge – Susie Blake, Peggy – Una Stubbs and Mildred – Sheila Reid

The old lady trio are best buds, with Marge as the bad-tempered leader, Peggy wowed by everything she sees, and Mildred in need of looking after by her pals.

Susie Blake is another Corrie alumni as Bev Unwin and also stars in sitcom Mrs Brown’s Boys. Una Stubbs is one of the stars of Sherlock, where she plays landlady Mrs Hudson. Sheila Reid featured in 80s hit Brazil and stars as Madge in comedy series Benidorm.

Ben – Javone Prince

Gemma’s ex-boyfriend Ben has trouble accepting that he is no longer a part of her life, despite being given a court order to stay away from her. He’s sure to clash with lovesick hero Terry.

Javone Prince is best known for a starring role in sitcom PhoneShop, but also created his own live sketch series The Javone Prince Show and eagle-eyed viewers may spot him in the forthcoming film Paddington 2.

Murder On The Blackpool Express airs on Saturday, November 11 on Gold.
