There is nothing quite like the experience of earning the acceptance of your in-laws. With an ensemble cast that includes McAdams, Diane Keaton, Dermot Mulroney, Luke Wilson, and Sarah Jessica Parker, "The Family Stone" is a comedy that many can relate to. Everett Stone (Mulroney) is in love with Meredith Morton (Parker), who is uptight and meticulous about everything. Everett's family is the complete opposite, and more on the laid-back, liberal side, which totally clashes with Meredith's personality. When Everett and Meredith visit his family for Christmas, everyone's personalities are front and center, making for an interesting and eventful holiday together. In the film, McAdams plays Amy Stone, the unapologetic, sarcastic sister of Everett.
