Fifteen Reasons Why and the Pursuit of Christ: Part 1

Reunion and Setup

 * In the film, Christopher runs into Ray Whitefield's younger sister, Hannah Whitefield (now Year 4), she hasn't changed appearance-wise since the third film.
 * Days later, when there were thirteen people at the outside benches in the Quads, Whitefield (on orders of later LokSat) set Christopher up on a date with Chloe White. While Christopher was the first to rise in the book, both Christopher and Chloe were the first to rise at the exact same time, defeating the purpose of Trelawney's prediction, but they were both later negatively impacted in such a way.

A Cover From The Truth

 * In the film, Christopher called Javier Esposito (NYPD) instead of calling 911 directly, which means the 911 Operator never appeared in this film. Also, he called from Snape's Office (with permission) and not from the Lookout Tower. This means Snape left the room to give him space.
 * When he first called, Captain Kate Beckett was on the line, Christopher has requested to speak with Javier.

The Midnight Tragedy

 * In the film, the tragedy suicide rates were not mentioned until the day before the official breakup took place.

The Breakup

 * In the book, he told Chloe about the breakup alone in the Trophy Room behind the Great Hall. In the film, he told her directly in the Great Hall, but managed to not rise commotion for the other students nearby.

Dumbledore's Death

 * In the film, Christopher was at Hogwarts the entire time the chaos took place instead of being in China (at the time of the murder).


 * In the film, Dumbledore was sniped by one of LokSat's henchmen instead of Dolohov killing him at close range. Two FBI agents (Chole White and Hannah Whitefield; both are working for Vice Unit Chief Victoria Gates) were still attacked, but Whitefield was thrown off the Astronomy Tower instead of Chole White.
 * Whitefield nearly died, but was saved by Christopher, who happened to be at the bottom of the Astronomy Tower (despite him working as a CIA Operative at the time)
 * Chloe White swapped roles with Whitefiled (for that scene), but instead of being stunned, as in the book, White was brutally assulted until IMA Agents and CIA operatives arrived.
 * Dumbledore instantly died upon impact of being shot, which means Dolohov alerted Christopher under the name of Dumbledore. This was confirmed by both Lanie Parish and Aaron Hotchner. In the books, Madam Pomfrey confirmed his death.
 * Dolohov was arrested after Bracken's arrest later in the film.

International Magical Affairs

 * Christopher joined the IMA after defecting the CIA because of LokSat's "Final Solution". This was never mentioned in the books.
