Chloe East, a rising star, shines in the horror film 'Heretic,' where she plays Sister Paxton, a Mormon missionary entangled in a sinister plot orchestrated by Hugh Grant's character. East initially feared the film would portray Mormonism negatively, but found it to be a nuanced character study instead. Co-star Sophie Thatcher, who plays Sister Barnes, also drew from her own Mormon background to shape her character, highlighting the diversity within the faith. The film raises theological questions while maintaining genre elements like a haunted house and a diabolical captor. Both actresses expressed a deep respect for their roles, aiming for authenticity in their portrayal of Mormon missionaries. East's performance has garnered praise from Grant, who noted her composure and fearlessness on set.
