8The Title

The Postcard Killings versus The Postcard Killers

Though it ’s a small change , it speaks to the subtle shift in view that the pic utilise over the script . The moving picture spend more time search for the sequential slayer and studying the murders they charge , piddle the scale of the investigation seem larger . Patterson is no stranger to let his workplace adapted , with hisAlex Crossnovels in the work to be movie and television show . However , The Postcard Killerswas a modest work for Patterson , as well as co - author Marklund , and it seems unlikely that either would be tip over at a alteration to the deed of conveyance .

Sincethe film focuses on Kanon ’s emotional journeying , it ’s only right that his experience of the killings is focus on , even in the title . This specialization could also be a way for the film to stand on its own two foot without the free weight of Patterson and Marklund ’s other body of work string up over its head . Using the believability of these authors as a merchandising strategy could have been utile , but it also could have hand spectator preconceived notions before they watched the motion-picture show .

7They Were On Vacation In London Instead Of Rome

Kim and Tom are on their honeymoon in London when they’re killed in the movie

When Kanon ’s girl and son - in - law are found murdered on their honeymoon it ’s in London , not Rome , and while both city are in Europe they ’re practically a world away in terms of ethnical differences . One reason the cinema might have chosen to start in London is the language barrier . Kanon is an NYPD ship’s officer , and his American style make frictionbetween himself and the European officers . However , have him start his journeying in London is less of a culture shock for an American than the rest of Europe , and allows an easy , and familiar , entrance into the world of the pic .

6The Only Killers Are Simon And Marina

As opposed to the art group formed by them in the book

One of the biggest reveals in the novel is that Simon ( Ruairi O’Connor ) and Marina ( Naomi Battrick ) are n’t the only killers . They started an outside crime ring of coupleswho similarly love graphics and have a predilection for violence . This is a huge development as the Holy Scripture Kanon enquiry how one couple could have committed every slaying . Though this is an challenging patch item , it would have made the film all the more perplexing . Limiting the murders to just Simon and Marina allowed their character reference to take precedence and for the story to be streamlined .

5Kanon’s Wife Is In The Movie

She goes unseen in the book

Valerie Kanon ( Famke Janssen ) is , unfortunately , one of the more pointless gain to the film . In an attempt to give Kanon more profundity , Valeria begs him to catch their daughter ’s killer and excite him from his natural depression - induced drunk semiconsciousness to stop him on his route of righteousness . After being used as essentially a tool to get Kanon going , she disappears from the narrativeonce he gets to Europe . She does n’t accompany him , or get in the agency of his family relationship with Lombard . Overall , the story would n’t have changed much if she had been left out .

4Dessie Lombard Is American

The Swedish reporter in the book becomes an American ex-pat

likewise to the shift in setting from Rome to London , Dessie Lombard ( Cush Jumbo ) , the newsman who team up up with Kanon when he arrives in Stockholm , is changed from a Swede to an American . This could have been to comfort the language barrier between Kannon and Lombard which built trust for the investigation . to boot , Lombard being American lessens the exoticization and sexualization of her characterthrough Kanon ’s eye . He had petty regard for the opinions of the European law enforcement he met along the room , and having Lombard be an American mean he treated her with more automatonlike respect .

3Kanon And Lombard’s Relationship Takes A Back Seat

Instead of being a focal point

Thoughromance in crime moviesrarely ends well , it ’s not surprising that the novel spends a lot of time on the bud relationship between Kanon and Lombard . However , the choice to make this secondary to Kanon ’s determination for retaliation was a strong shift in the narration . It ’s clear through the characterization of Kanon ’s human relationship with both Lombard and his wife , Valerie , thatthe only individual he ever really cared for in this life was his daughter . Outside this , it also let Lombard to be a more fully developed fictitious character , instead of just a love interest .

2The Killers' Identities Aren’t Revealed Until Halfway Through

Their identities are known from the start of the book

The first step conniption of the novel commence with a description of the siblings seducing and polish off a couple in a European hotel way . While neither the film nor the Koran operates as a mystery story and is more focused on Kanon ’s journeying to trance the sea wolf , the film uses the reveal of their identity element as a thrilling twist . Using another mysterious couple as a cherry-red Clupea harangus for the audience , the innocent people are lead suspectsfor Kanon and Dessie until they turn up dead . It ’s then that all eye grow to Simon and Marina , and the real chase start .

It ’s then that all eyes change by reversal to Simon and Marina , and the real chase start .

1Simon And Marina’s Father Is In Prison

The siblings' parents were murdered in the book

In both the film and the record book , Marina and Simon are incite by the treatment and abuse they faced as tyke at the hands of their parent . However , in the film , their forefather is an elite whitened - neckband criminal who is in prisonfor misappropriation . He is a imagination for Kanon and Lombard as he leave perceptiveness into why the siblings are on their offence spree . Additionally , his descriptions of their puerility and the way he raise them give a important account for how two seemingly normal children drop into a murderous , incestuous family relationship .

Though the parents are still a motivating factor for the crimes in the novel , they are both dead , having been murder . The remainder in the pic might have beenan attempt to solve the novel ’s trouble of not full acquire Simon and Marina as charactersand in full explore their motivations . Their backstory is broadly speaking flesh out in the novel , but including the father in the film not only provides expounding about the siblings but also gives an chess opening for a sequel film if needed .
