Her cameo in The Princess Diaries 2: Royal Engagement remains an insider favorite for cinema trivia buffs. Director Garry Marshall was known for casting relatives of his lead stars in charming background parts. Because Anne was leading the franchise as Mia Thermopolis, Marshall invited Kate to portray the choir director during the cathedral scenes, allowing mother and daughter to share a frame in one of Disney's flagship live-action franchises.
Four years later, when director Jonathan Demme filmed the raw, documentary-style indie drama Rachel Getting Married, he cast Kate McCauley Hathaway as Emma. The film, which earned Anne her first Academy Award nomination for Best Actress, relied on loose, improvisational scenes among close-knit ensemble actors, making Kate's presence an asset during the high-tension wedding weekend sequences.
