‘The End of Oak Street’ Twist Ending Explained: Two Jeannettes and a Spacetime Rift

David Robert Mitchell's film 'The End of Oak Street' concludes with a subtle but shocking twist involving a spacetime disruption that creates duplicate characters. The film, set in the 1980s, follows the Platt family—Denise (Anne Hathaway) and Greg (Ewan McGregor)—whose marriage is strained by Greg's secret pizza delivery job and drinking, and Denise's dissatisfaction. Their suburban town of Flowervale is transported to prehistoric times due to wormholes, forcing the family to survive among scientifically accurate feathered dinosaurs. Greg sacrifices himself to save his family, being devoured by an Allosaurus. Denise leads her children and orphaned neighbor Jeannette (Jordan Alexa Davis) through a wormhole back to 1982, twenty minutes before the event. She warns neighbors and orders a pizza to lure Greg away from the danger. The film ends with the family reunited and seemingly happy, but the final scene reveals two Jeannettes at a neighborhood barbecue—one from the timeline that experienced the anomaly and another saved by the warning. This implies two timelines exist, raising questions about duplicates and the fate of alternate versions of the characters. The film leaves these implications unresolved, focusing on the existential and familial consequences of the duplication.
