9 BIG WAYS THE ALLEGIANT FILM IS DIFFERENT TO THE VERONICA ROTH BOOK

It\'s a cold, hard fact for book fans that when your favourite story gets the go-ahead for the big screen, there\'s ALWAYS going to be differences between the version of a story on the pages, and the movie version which reaches Hollywood. 

It can be fairly life-ruining, but there\'s just never enough room on screen and stuff has to be tweaked and cut - and the 

 movie is taking the book-to-screen changes to a WHOLE new level, and if you love what Veronica Roth wrote for Tris and Four, you\'re gonna be in for some big surprises. Here\'s the 9 big ways that things are different.

The Allegiant film won\'t be introducing you to Cara, Matthew, Nita, Amar, David, and the rest of the Bureau of Genetic Welfare - probably because there just ain\'t time. Instead, loads of \'em get the chop, and some are lumped with others into super-roles. 

Matthew is just a driver. You don\'t meet Tori\'s brother, so after she dies while trying to escape Chicago, no one ever really mourns her (soz). Amar, Four\'s teacher in Dauntless before he staged his own death, never makes an appearance either - meaning we never see the unsure, young side of Four.

In the books, brainy Tris wises up to David\'s plan and tries to stop him, but the film sees David actually convince Evelyn to release the memory serum to the town instead of just himself. She has a crisis of confidence though and changes her mind, and actually, her whole rise to power is completely different on screen.

When the Divergent series met Hollywood, this one was always gonna happen, just to jazz things up a bit and make him the typical \'hot action man\' kind of guy. Rather than spend his time plotting and discovering the O\'Hare landscape, Four jumps in true Dauntless style to kill soldiers all over the place. He\'s beautiful and badass and basically Hollywood-ised - not really the guy we meet in the books. Sidenote: he never even asks Tris to call him Tobias in the films. Eh?

In the book, the group are sent to stay in an old airport conference room, and over time they drift apart from each other. But in the film, they\'re thrust into society and put straight to work, presumably to keep things more fast paced.

Caleb, Christina, and Peter all take on waaay more significant roles in the bureau. Christina and Tris don\'t have time to fight about their differences. Tris relies on the brother she can\'t stand to be around much sooner than she does in the book. Tris, Four, Christina, Peter, and Caleb never chill - literally ever.

5. O\'Hare and The Fringe probably don\'t look how you imagined.

The area outside Chicago was described a kind of desolate wasteland, but instead it\'s some kind of weird, Mars-inspired, dystopian world. The fictional O\'Hare looks nothing like the IRL airport either. As for the Fringe, it looks like a number of smallish tent cities, and not an overgrown wilderness. It\'s obviously CGI central, a ton of new gadgets and devices too, that aren\'t really explained or necessary - they\'re just reeeal jazzy and fun to play with.

6. THAT steamy scene (and there\'s no break up).

Oh don\'t pretend like you don\'t know which one we\'re on about. Veronica Roth won\'t admit whether Tris and Four DID IT, but it definitely reads like they did. Well, that already happened in the second film Insurgent, so this time the pair have shedloads of up-close moments to make the movie half crazy action, half steamy romance. They\'ve also ditched the hardcore break up which features in the book - but maybe that\'s just because no one sane would break up with Theo James. No one.

And much, much sooner than they do in the book, where Tris never goes back because her \'home\' doesn\'t exist for her anymore. Instead of cooly figuring out all the lies and motives of the Bureau, she and Four rush in to save their city, do more arse-kicking and save Evelyn. 

In the books, we wanted to rip the pages out and shove them down his gob, but the movie has given Peter a slightly different angle. His allegiance to the powers that be shift significantly, and there\'a s sense he\'d want to use the memory serum to give himself a fresh start - he actually seems pretty terrified by the prospect of using it.

Yep, the shocking, heart-wrenching ending you know from the books hasn\'t made it to the end of the Allegiant film, which basically means that it\'s an entirely different plot. But of course, the Hollywood big cheeses decided to split this book into two parts, meaning that the ending isn\'t REALLY the ending. Fans have always been pretty infuriated by Veronica Roth\'s decision to kill off Tris and in fact, the tagline for the final movie Ascendant, is \'The End Is Never What You Expect.\'

What did you reckon to the changes in the Allegiant movie? Reckon they should have stuck closer with the books, or did you like the new ideas? Let us know with a tweet to @Sugarscape.
