The role of Japp is played by
Philip Jackson in the British TV series ''
Agatha Christie's Poirot'', where
Hercule Poirot's character is played by
David Suchet. Before Suchet took on the role of Poirot, he had previously played Japp himself in the
1985 film Thirteen at Dinner, where
Peter Ustinov played Poirot. Philip Jackson portrays Japp as working-class and 'thoroughly British', not very intelligent but an extremely diligent, canny and active police officer with a good but rather dry sense of humour, characteristics which often serve as a perfect
foil to Poirot's personality, who is intelligent, elegant, upper-class but rather slow in movements and of a very serious nature. In the same television series, Japp is already a Chief Inspector in the first episode, his full name is James Harold Japp according to the episode "The Chocolate Box", and he has been promoted to Assistant Commissioner by the time he appears in the episode "The Big Four". Philip Jackson is also one of the actors who played Japp in the
BBC Radio adaptations of Poirot stories, produced contemporaneously with the Suchet TV series and starring
John Moffatt as Poirot. In the radio dramatisations, Inspector Japp was played by
Norman Jones in
Lord Edgware Dies (1992), by Philip Jackson in
The ABC Murders (2000),
Death In The Clouds (2003),
One, Two, Buckle My Shoe (2004), and
The Mysterious Affair at Styles (2005), and by
Bryan Pringle in
Peril at End House (2000). Japp is played by
Melville Cooper in the
1931 film adaptation of Christie's stage play
Black Coffee. As the inspector's name is spelled similarly and pronounced in the same way as the ethnic slur
Jap, he was renamed in the Japanese
anime series ''
Agatha Christie's Great Detectives Poirot and Marple'' (
NHK, 2004). In the
Professor Layton series of puzzle video games for the
Nintendo DS and
Nintendo 3DS, the fictional
Scotland Yard chief inspector Chelmey appears visually and contextually as a comically incompetent caricature of Inspector Japp as played by Philip Jackson. A retired Japp is played by
Kevin McNally in
The ABC Murders (2018); the series starts with Japp dying of a heart attack, and a recurring sub-plot is Inspector Crome, Japp's protégé, expressing distrust of Poirot as he feels that working with Poirot ruined Japp's career. ==References==
