The film 'Firebrand' brings attention to Queen Katherine Parr, the often overlooked survivor among King Henry VIII's six wives. While the movie aims to highlight her story, some critics find it lacking in portraying her inner life and motivations adequately. Alicia Vikander and Jude Law, who play Katherine Parr and Henry VIII, respectively, express the importance of shedding light on historical women like Parr and the challenges they faced. Despite mixed reviews on the film's execution, the performances of the cast, particularly Vikander and Law, are recognized as strong and dedicated to their roles, emphasizing the struggles and complexities of the characters they portray.
