Later in 2004, McAdams starred opposite fellow Canadian Ryan Gosling in the romantic drama The Notebook, based on Nicholas Sparks' novel of the same name. She played Allie Hamilton, a wealthy Southern belle who has a forbidden love affair with Gosling's poor labourer, Noah Calhoun. McAdams spent time in Charleston, South Carolina, prior to filming to familiarize herself with the Southern accent, and took ballet and etiquette classes. Filming took place from late 2002 to early 2003. Although McAdams and Gosling became romantically involved in 2005, they had a combative relationship on set. "We inspired the worst in each other," Gosling has said. "It was a strange experience, making a love story and not getting along with your co-star in any way." At one point, Gosling asked the film's Director Nick Cassavetes to "bring somebody else in for my off-camera shot" because he felt McAdams was being uncooperative. Stephen Holden of The New York Times praised the "spontaneous and combustible" performances of the two leads while Roger Ebert of the Chicago Sun-Times was won over by the "beauty and clarity" of McAdams's performance. Michael Wilmington of the Chicago Tribune declared her "a real discovery" who "infuses young Allie with that radiant, breathlessly winning ingénue grace and charm that breaks hearts". The film grossed over $115 million worldwide. McAdams won an MTV Movie Award and four Teen Choice Awards. Entertainment Weekly has said that the movie contains the All-Time Best Movie Kiss while the Los Angeles Times has included a scene from the film in a list of the 50 Classic Movie Kisses. The Notebook has appeared on many Most Romantic Movies lists. "I'm so grateful to have a film that people respond to in that way", McAdams told Elle in 2011. "It was a big deal."
