With Harry Potter and the Goblet of Fire (2005), both Watson and the Harry Potter film series reached new milestones. The film set records for a Harry Potter opening weekend, a non-May opening weekend in the US, and an opening weekend in the UK. Critics praised the increasing maturity of Watson and her teenage co-stars; The New York Times called her performance "touchingly earnest".  For Watson, much of the humour of the film sprang from the tension among the three lead characters as they matured. She said, "I loved all the arguing. . . . I think it's much more realistic that they would argue and that there would be problems. " Nominated for three awards for Goblet of Fire, Watson won a bronze Otto Award.  Later that year, Watson became the youngest person to appear on the cover of Teen Vogue, an appearance she reprised in August 2009.  In 2006, Watson played Hermione in The Queen's Handbag, a special mini-episode of Harry Potter in celebration of Queen Elizabeth II's 80th birthday. 
By the age of ten, Watson had performed in various Stagecoach productions and school plays, including Arthur: The Young Years and The Happy Prince ,  but she had never acted professionally before the Harry Potter series. Following the Dragon School, Watson moved on to Headington School .  While on film sets, she and her peers were tutored for up to five hours a day.  In June 2006, she took GCSE school examinations in ten subjects, achieving eight A* and two A grades.  
According to an interview with Entertainment Weekly , the former Harry Potter star says her character — Belle — has an all-new backstory in the live-action remake of Beauty and the Beast.
