There are several nods to Christie’s authorship dotted throughout the film, including direct references to Hercule Poirot and the main character buying the latest Christie novel at a book shop at the start of the film.
What I am wondering is whether the title Invitation to a Murder is another such nod. The reason I think this may be the case is that in certain countries, one of Agatha Christie’s Miss Marple novels, A Murder Is Announced, was published under a title that directly translates to ‘invitation to (a) murder’; for example Invitation til mord in Danish and Invitasjon til mord in Norwegian.
My attempts at Googling has brought up no relevant information or hints as to whether it actually is a reference.
Has anyone from the film’s production commented on this? Is it known if the title is a deliberate nod to Christie, or if it’s just coincidence?
