Gaining Access to the Study Records
As they were making the documentary, the team helped the brothers fight for access to the study’s records. “We were driven by the injustice on behalf of the brothers,” director Wardle stated. “(Producer) Becky (Read) spent nine months working with the brothers to access the material … files and footage that should rightfully be theirs.”

After months in pursuit, the brothers got their hands on about 11,000 pages of records – information that hadn’t been seen in decades. But it wasn’t all seen in the film. Why? Because it was released after the film was finished.
