Clive Exton in partnership with producer
Brian Eastman adapted the pilot. Together, they wrote and produced the first eight series. Exton and Eastman left
Poirot after 2001, when they began work on
Rosemary & Thyme. Michele Buck and
Damien Timmer, who both went on to form
Mammoth Screen, were behind the revamping of the series. While Christie's novels are set contemporaneously with the time of writing (between the 1920s and 1970s), 1936 was chosen as the year in which to place the majority of early
Poirot episodes; references to events such as the
Jarrow March were included to strengthen this chronology. With some exceptions, the series as a whole is set roughly in chronological order between 1935 and 1939, just prior to the
Second World War. Numerous references in early episodes place the series primarily in 1935, progressing to 1936 by series four. Most references remain in 1936, moving slowly forward to 1937 by series eleven and 1938 by
Murder on the Orient Express.
The Big Four is set explicitly in early 1939. The most notable exceptions to this chronology are
The Mysterious Affair at Styles, which narrates Poirot's first case in 1917, and ''
Curtain: Poirot's Last Case, which is set primarily in 1949. The Chocolate Box'' shows Poirot in the early 1900s, though the framing narrative remains consistent with the series' usual timeframe. The opening titles were designed by Pat Gavin, and feature
Art Deco–
Cubist–style iconography, partly inspired by
Cassandre, including images of
Battersea Power Station, biplanes, boats, and a train with Poirot's name formed by the wheels. The episodes aired from series 9 in 2003 featured a radical shift in tone from the previous series. The humour of the earlier series was downplayed, with each episode being presented as serious drama and saw the introduction of gritty elements not present in the Christie stories being adapted. Recurrent motifs in the additions included drug use, sex, abortion, homosexuality, and a tendency toward more visceral imagery. The visual style of later episodes was correspondingly different: particularly, an overall darker tone; austere modernist or
Art Deco locations and decor that were widely used earlier in the series were largely dropped in favour of more elaborate settings (epitomised by the re-imagining of Poirot's home as a larger, more lavish apartment). The series logo was redesigned (the full opening title sequence had not been used since series 6 in 1996), and the main theme motif, though used often, was usually featured subtly and in sombre arrangements; this has been described as a consequence of the novels adapted being darker and more psychologically driven. returned for two episodes of the final series (
The Big Four and
Curtain), with Philip Jackson and Pauline Moran returning for the adaptation of
The Big Four. Zoë Wanamaker also returned for the adaptations of
Elephants Can Remember and ''Dead Man's Folly''. Clive Exton adapted seven novels and fourteen short stories for the series, including "
The ABC Murders" and "
The Murder of Roger Ackroyd", which received mixed reviews from critics.
Anthony Horowitz was another prolific writer for the series, adapting three novels and nine short stories, while
Nick Dear adapted six novels. Comedian and novelist
Mark Gatiss wrote three episodes and also guest-starred in the series, as have
Peter Flannery and
Kevin Elyot.
Ian Hallard, who co-wrote the screenplay for "The Big Four" with Mark Gatiss, appears in the episode and also in "Hallowe'en Party", which was scripted by Gatiss alone.
Florin Court in
Charterhouse Square,
London, was used as Poirot's London residence, Whitehaven Mansions. The final episode to be filmed was "Dead Man's Folly" in June 2013 on the
Greenway Estate (which was Agatha Christie's home) broadcast on 30 October 2013. Most of the locations and buildings where the episodes were shot were given fictional names.
Casting Suchet was recommended for the part by Christie's family, who had seen him appear as Blott in the TV adaptation of Tom Sharpe's
Blott on the Landscape. Suchet, a
method actor, said that he prepared for the part by reading all the
Poirot novels and every short story, and copying out every piece of description about the character. Suchet told
The Strand Magazine: "What I did was, I had my file on one side of me and a pile of stories on the other side and day after day, week after week, I ploughed through most of Agatha Christie's novels about Hercule Poirot and wrote down characteristics until I had a file full of documentation of the character. And then it was my business not only to know what he was like, but to gradually become him. I had to become him before we started shooting". During the filming of the first series, Suchet almost left the production during an argument with a director, insisting that Poirot's odd mannerisms (in this case, putting a handkerchief down before sitting on a park bench) be featured; he later said "there's no question [Poirot's]
obsessive-compulsive". According to many critics and enthusiasts, Suchet's characterisation is considered to be the most accurate interpretation of all the actors who have played Poirot, and the closest to the character in the books. In 2013, Suchet revealed that Christie's daughter
Rosalind Hicks had told him she was sure Christie would have approved of his performance. In 2007, Suchet spoke of his desire to film the remaining stories in the canon and hoped to achieve this before his 65th birthday in May 2011. Despite speculation of cancellation early in 2011, the remaining books were ultimately adapted into a thirteenth series, adapted in 2013 into 5 episodes, from which "Curtain" aired last on 13 November. A 2013 television special,
Being Poirot, centred on Suchet's characterisation and his emotional final episode.
