Actress Jennifer Love Hewitt portrayed Julie in the Kevin Williamson-scripted feature film I Know What You Did Last Summer (1997), in which she is the final girl.
She is a high school senior who was involved in a hit-and-run accident of a cycling boy with her boyfriend Ray Bronson, and friends Barry Cox and Helen Rivers.
Despite Ray's attempts to reassure her, Julie's instincts drive her to seek answers, further reinforced when she visits Helen, hoping for comfort and support.
During their visit to the Gregg household, Julie engages in conversation with Megan, David's mother, hoping to glean information about the mysterious note.
Through their conversation, Julie learns more about the impact of David's death on the Gregg family, deepening her empathy for their grief.
As the tension escalates, Julie's instincts lead her to suspect Collie, a new acquaintance of Helen's, as the perpetrator behind the threats.
In a climactic confrontation, Julie finds herself in mortal danger as Collie, now revealed as Bud, attempts to kill her.
Throughout the harrowing ordeal, Julie undergoes a profound transformation, emerging as a resilient and courageous young woman.
Her unwavering determination to uncover the truth and confront her fears ultimately leads to her survival and newfound strength.
Returning to her hometown, she reunites with Helen, Barry, and Ray, telling them that the man they hit was named David Egan and that his death was labeled an accidental drowning.
Ray catches up to their boat and saves Julie by cutting Ben Willis's hand off and sending him overboard.
Jennifer Love Hewitt appeared in a cameo in the Boy Meets World episode And Then There Was Shawn in which she parodied a scene where Julie shouts in the 1997 film.
