Lost Girls
What's the Story?
The Gilbert family is clearly struggling in LOST GIRLS. Mari (Amy Ryan) is a single mom with three daughters living in Long Island. She works two jobs to support her family and is exhausted and stretched thin. Her youngest daughter, Sarra (Oona Laurence), a preteen, is prescribed meds to stabilize her behavioral issues. When Mari's eldest, Shannan (Sarah Wisser), doesn't join her family for dinner as planned, Mari is concerned. Though she's a young woman living on her own, it's unlike Shannan not to let Mari know where she is. After a number of unanswered cellphone messages and no word from Shannan for two days, Mari goes to the local police for help. Having to acknowledge that Shannan is a sex worker is difficult for Mari, and while it's not wholly surprising, it upsets her younger sisters Sherre (Thomasin McKensie) and Sarra. Though one supervising police officer (Gabriel Byrne) has good intentions, others are unsympathetic and disinterested. Shannan's "sex worker" way of life seems to imply that the young woman was self-destructive rather than vulnerable. Mari's relentless advocacy for her missing daughter leads to the discovery of the bodies of four female sex workers -- Shannan isn't among them -- buried on a beach, setting off a search for a serial killer.
Is It Any Good?
Centering upon one victim of a real serial killer, this well-made, thought-provoking, and heartfelt film raises awareness of how the marginalized people in our society suffer at the hands of many. Liz Garbus, noted for her documentary films, has transitioned to narrative filmmaking with a project that works well for her and shows her passion. The slow reveal of the depths of Mari Gilbert's struggle and the lack of resources available to her and to the families of the other victims is frightening. In the final moments of Lost Girls and in the postscript to the Gilbert family's true story, the tragedy doesn't let up, revealing that happy endings are a rarity in some broken lives, even for a woman as dogged and smart as Mari Gilbert.
Talk to Your Kids About ...
Families can talk about the value of making movies out of true-life stories. Lost Girls is "inspired" by a true story. Would you say that the filmmakers adapted Mari Gilbert's story to entertain, inform, persuade, or inspire action from its audience? Or is it a combination of those? What was your takeaway from the film?
Though there was no actual on-camera violence in the movie, were you ever frightened? Was it suspenseful? How did the filmmakers use unseen violence to heighten the tension?
The production design (locations, settings, costumes, colors, and lighting) is an integral element in movies. How did the production design in Lost Girls contribute to your understanding of the people involved, the mood, and the movie's viewpoint? Pick one location (e.g., the beach, the Gilbert's house) and describe the design and what it was meant to convey.
