Elle Fanning (left) poses with sister Dakota Fanning at the 2007 Sundance Film Festival. The particular occasion was the after-party for the world premiere screening of the film Hounddog. This was in Park City, Utah on January 22, 2007. Hounddog was a coming-of-age drama that starred Dakota Fanning; Elle Fanning did not appear in the film. Dakota Fanning was born in 1994, and Elle Fanning was born in 1998, so they turned 13 and 9 years old, respectively, the year this photo was taken.
