It’s no surprise that Agatha Christie is the best selling fiction writer of all time and that her books are ripe for TV and film adaptation.

Whether they’re set in an exotic location like Egypt or in a quiet country village, Christie’s timeless tales of greed, love and murder still provide thrilling escapism - and a gripping finale as the killer - or killers - are revealed.

Since the publication of her first book, The Mysterious Affair at Styles, in 1920, demand for her quintessentially English mysteries has always been high. In 1928 the first film adaptation of a Christie story, The Passing of Mr Quin, was released and they’ve kept coming ever since.

In 2017, Kenneth Branagh directed a start-studded adaptation of Christie favourite Murder on the Orient Express, and followed it up with this year's Death on the Nile. Hugh Laurie, meanwhile, picked a lesser-known Christie title - Why Didn’t They Ask Evans? - off the shelf to adapt and direct an entertaining mini-series for BritBox.

In total, Christie - who died in 1976 aged 85 - wrote 66 novels and 14 short stories, many of which have found their way onto screens big and small. We take a look at the pick of the recent crop of Agatha Christie adaptations.

Why Didn’t They Ask Evans? (2022)

Based on the 1934 novel of the same name, this charming adaptation was written and directed by actor Hugh Laurie who also plays a minor role.

The mystery begins with the death of a man whose enigmatic dying words, “Why Didn’t they ask Evans?”, set in motion a twisty tale of murder and subterfuge. Honourable but pennyless vicar’s son Bobby Jones and the feisty Lady Frances become tangled up in the case and decide to unravel the mystery for themselves.  

The three-part drama stars Will Poulter and Lucy Boyton and includes cameos by Emma Thompson, Jim Broadbent and an aptly chosen part for Paul Whitehouse as the landlord of the Angler’s Arms.

Death on the Nile (2022)

A sumptuous second Agatha Christie adaptation from Kenneth Branagh who once again dons the fabulous moustache to play the Belgian detective.

Joining a honeymooning couple and their entourage on a cruise down the Nile, Poirot soon has to solve a handful of murders and unravel a tale of deception and greed.

Starring Kenneth Branagh, Gal Gadot, Russell Brand, Sophie Okonedo, Dawn French and Jennifer Saunders.

The Pale Horse (2020)

Screenwriter Sarah Phelps' fifth and final Christie adaptation for the BBC has a very sinister air, set between 1960s swinging London and the creepy country village of Much Deeping, a place with more than a hint of The Wicker Man about it.

Rufus Sewell plays Mark Easterbrook, a grieving husband who finds himself unhappily married to Hermia, a former friend of his first wife.

Easterbrook’s world is turned upside down for a second time when his name appears on a list found on a murdered woman. The other names on the list are turning up dead - could Easterbrook be next? And could this be the supernatural work of witches? Zachariah Osbourne, played by an unrecognisable Bertie Carvel, certainly thinks so, but this is Agatha Christie and all is not always as it seems.

Also stars Kay Scodelario and Claire Skinner.

The Pale Horse is available to buy on Prime Video

ABC Murders (2018)

Hollywood A-lister John Malkovich stars as an aging Hercule Poirot, a once adored detective now out of favour with the police and general public.

Sarah Phelps’ screenplay and Malkovich's presence bring a gravitas to the role and he presents a more brooding character than other portrayals of the Belgian sleuth.

The action takes place in 1933, when Poirot receives a letter, signed off with the letters ABC, detailing a murder that is about to take place. At first the police think it’s an April Fool's joke, then suspect Poirot knows more than he’s letting on. Meanwhile we see an awkward travelling salesman by the name of Alexander Bonaparte Cust visiting all the victims prior to their murders.

With the police proving unhelpful, it’s down to Poirot to solve the murders and regain his standing in an unforgiving and mistrusting pre-war Britain.

Starring John Malkovich, Rupert Grint, Shirley Henderson and Andrew Buchan.
