Why read this guide
This book and film comparison separates the jealousy plot from the spiritual argument beneath it. The film makes the romance immediate, while the novel gives Bendrix's hostile, unreliable voice more room to resist what he finds.
PlotGeeks note
Neither version offers an easy conversion story. Bendrix's anger matters because it may be the closest he can come to addressing the God he says he rejects.
At a glance
Remember this
The key comparison is how the book version of The End of the Affair changes in its film version. The main change is the film foregrounds the love story, while the film reduces some theological and secondary material to keep Sarah and Bendrix's relationship at the center.
Closer comparison
Bendrix's narration continually turns investigation into argument and self-exposure.
The affair and wartime separation receive more direct emotional emphasis.
Her diary revises Bendrix's account and opens the religious dimension from inside her thinking.
Performance and flashback bring her fear, bargain, and sacrifice into the romantic present.
Bendrix's final address to God is bitter, resistant, and impossible to reduce to certainty.
The same conflict lands after a more visibly tragic romance, making grief the strongest path into it.
