How & Why the ‘One Day’ Series Was Different From the Movie — Including That Ending

[Warning: The below contains MAJOR spoilers for One Day, Episodes 1-14.]

Netflix‘s new series One Day may be based on David Nicholls’ 2009 novel of the same name, but it isn’t the first onscreen adaptation of the book as Anne Hathaway and Jim Sturgess took on the roles of Emma Morely and Dexter Mayhew — now filled by Ambika Mod and Leo Woodall in the show — in the 2011 film.

While the core structure of the story is the same, there are definitely some big differences between the adaptations, as Emma and Dexter’s story unfolds over the years against the day of July 15.

Below, we’re breaking down some of the most obvious changes in the show, which saw Nicholls serve as an executive producer and writer.
