her acting career by playing the younger version of her older sister Dakota's characters in the miniseries Taken and the movie I Am Sam. In 2002, at the age of four, Fanning won her first role independent of her sister in the comedy Daddy Day Care. Anecdotal evidence of her emerging skill was seen in the decision to cast her in the role of Ruth in The Door in the Floor (2004) opposite Jeff Bridges and Kim Basinger. The film's producers originally planned to hire identical twins for the intense shooting schedule, but were so impressed with Fanning that they used only her. Late in 2003, Fanning appeared in Because of Winn-Dixie in the small role of Sweetie Pie Thomas. In 2004, she did voice work in the English-dubbed version of Miyazaki's animated film My Neighbor Totoro, in the role of Mei, opposite Dakota, who voiced Satsuki, the older sister to Elle's character. Later that same year, she filmed I Want Someone to Eat Cheese With. In early 2005, Fanning filmed scenes in Charlotte's Web as the "future granddaughter" of Fern Arable played by Dakota. However, the scenes did not make the final cut. In mid-2005, she played Debbie, the daughter of Richard and Susan Jones (played by Brad Pitt and Cate Blanchett) in the film Babel. In early 2006, Fanning filmed scenes in both The Nines and Déjà Vu. In mid-2006, she filmed The Lost Room, a science-fiction TV miniseries. Also in 2006, she appeared on the episode "Need to Know" of House: MD, playing the patient's daughter. She appeared in an episode of Criminal Minds in 2006, playing the supporting role of Tracey in "The Boogeyman". By the end of 2006, Fanning began to book lead roles. The first of these was the one of Emma Learner in Reservation Road—the grieving daughter of Grace and Ethan Learner. The film deals with the aftermath of a tragic car accident in which Emma's brother is killed. In early 2007, Fanning reunited with her Babel co-stars, Brad Pitt and Cate Blanchett, in a small part in The Curious Case of Benjamin Button as the younger version of Blanchett's character. Mid-year 2007, Fanning filmed the title role Phoebe of Phoebe in Wonderland, which also starred Felicity Huffman and was released in March 2009. From July through October 2007, Fanning appeared in The Nutcracker in 3D, playing Mary. The movie was filmed in
