Reader Player One: 10 Biggest Changes From The Book

As well as giving new roles to Samantha and Daito, the climax of Ready Player One deviates from the novel in another vital respect: the High Five stage their final assault from haptic suits set up in the back of Aech (Lena Waithe)'s van.

This is a significant deviation from the novel, wherein the High Four (Daito, remember, was originally killed off) reach the final key in top-of-the-range gear and total security, in the home of the OASIS's co-creator Ogden Morrow.

Not only do we not see Morrow's luxurious mansion and estate in the movie, we don't even meet the man himself (Simon Pegg) in the flesh until Wade/Parzival has successfully found the Easter Egg, and agrees to ownership of the OASIS on the condition that it is split equally between the High Five.

This change works on a number of levels. For one, it again allows for a more cinematic finale: the stakes are higher with the characters still facing peril in the real world, and the jerking motions of the van make their struggle within the OASIS ever greater.

Moreso, by completing the challenge not from the safety and comfort of a rich man's home, but back where it all began for Wade - the stacks - it hammers home the point that the young and underprivileged can affect real change all on their own: a worthy moral, perhaps missing in the novel.

Even so, Morrow has helped them more than a little in his disguise as the custodian of the archive - and by giving Parzival his dearly-needed extra life.
