"The Idea of You" star Anne Hathaway and the rest of the cast walked a red carpet at the movie's premiere at SXSW in Austin on Saturday. The film follows the story of a romance between a 40-year-old professional and mom, Hathaway, and a 24-year-old boy band star, played by Nicholas Galitzine. A crowd of screaming fans gathered for a glimpse of the movie stars, to which Hathaway said, "I love you so much. I will never forget this screening. Thank you so much."
