In Apple Cider Vinegar, Hek is the PR crisis manager Belle hires after her fraud is exposed. In real life, Belle Gibson was helped by crisis manager Alex Twomey (now known as Titus O'Reily), although he worked pro bono — and doesn't appear to have anything else in common with the fictional character Hek.

The actress plays Belle Gibson, an Australian wellness guru who claims to have cured her own terminal brain cancer through a healthy diet and other "natural" treatments.

Why do so many people follow wellness influencers, even if they don’t have many or any qualifications? It makes sense with the gaps in health care, doctors say.
