What's the Story?

THE INVESTIGATION OF LUCY LETBY recounts the story of mysterious infant deaths in an understaffed UK neonatal hospital unit. Prosecutors build a speculative case based on circumstantial evidence suggesting that nurse Lucy Letby was responsible for deliberately causing seven deaths. The filmmakers use AI-generated interviewees, some of them teary-eyed, to comply with court-ordered protection of the identities of people reluctant to speak on camera.

Is It Any Good?

Kids say ( 2 ):

Given the use of AI to "create" characters making assertions about Lucy and the case, this feels like an exercise in hoodwinking. One "character" is a mom (her name is changed) who lost her baby. Her AI-generated presence is used throughout the film for great emotional effect. Surely, filming her in shadow would have been just as protective of her identity. The decision to instead make up an avatar for her muddies all the film's conclusions. The use of AI leads to the question of how much of what the fake mom says is real or altered to emphasize and represent the grief of parents who lost babies.

The Investigation of Lucy Letby does present newly-released police body cam footage of Lucy's arrests and her police interrogations, which seem like invasions of privacy, especially arrests at her home. Prosecutors point to the seemingly damning drop in baby deaths after Letby is fired but, post-trial, others attribute that fact to the hospital losing its status as a destination for highly critical cases, where a higher rate of mortality is built-in. Lots of filler adds to the running time, as when the AI-altered mom reports, "Waiting for the verdict was very stressful." All in all, the movie certainly demonstrates how easy it is to skew a case against what may be an innocent person.

Talk to Your Kids About ...

  • Families can talk about the danger of using AI-created "characters" to manipulate viewers' emotions with regard to an accused murderer. Does this create a bias?

  • How might the use of AI influence our view of Lucy's guilt or innocence?

  • How does the movie add to the debate on the use of "deep fakes" on the internet and social media?
