Dunham’s Catherine Called Birdy is much more plotted than the novel, which centers on the drama surrounding the impending marriage of its titular character, played by Bella Ramsey, a scene stealer from Game of Thrones’ later seasons. If you didn’t make it far enough in the doomed HBO show, Ramsey’s turn in Birdy will be a pleasant surprise: she is an exciting, capable newcomer whose performance is devoid of technical theatrics or youthful preening.
