How old was Emmy Rossum as Katie Markum in Mystic River?

13 years earlier, she gained recognition for her role in the 2003 American neo-noir mystery crime drama film Mystic River. Directed and scored by Clint Eastwood, she starred as James “Jimmy” Markum’s (Sean Penn) 19-year-old daughter Katie Markum.

Katie is secretly dating Brendan Harris (Tom Guiry), a boy from a family Jimmy despises. After going out for the night with her girlfriends, she ends up being murdered.

Nominated for numerous awards and a box office success, the film was released on October 15, 2003, just one month after Emmy Rossum turned 17. Born on September 12, 1986, in Sunset Park, New York, she celebrated her 17th birthday on September 12, 2003.

“It was thrilling,” Rossum told PopEntertainment in an interview in 2007.

“I auditioned for that. I sent Clint Eastwood a tape of me reading the character’s part on a little video camera. I got cast off that. I didn’t meet anybody until I walked on the set the first day. It was very surprising and exciting. The same day I got that call that I got Mystic River, I got the part in The Day After Tomorrow as well. I was flying back and forth between the two projects and everything had just taken off,” she added.

“It was very exciting being a part of a small film like Mystic River, which I really felt was such an important cast and such an important learning experience for me. Also to be part of something like Day After Tomorrow, which was, I felt, so ecologically important… I always have tried to really take the jobs that I really believed in and never tried to do something I didn’t really want to do.”

Principal photography took place on location in Boston when Emmy Rossum was 16.

Sam looked neat in a black suit with a white shirt and a black tie underneath, while his fiancée looked classic in a black dress.

The Phantom of the Opera actress wore a simple and classy black sleeveless dress by Dior. Her form-fitting frock featured a scooped neckline and a sparkling, sequined inset that gave it a chic twist.

The “Shameless” star added further sparkle and glamour to the look by wearing some jewelry, including a pair of diamond earrings, a bracelet, and her engagement ring. Emmy’s best accessory, though, was her megawatt smile.

She wore her hair in a slicked side-parted updo and sported flawless makeup with shimmering pink lipstick.

To complete her look, Emmy carried a metallic Lee Savage clutch that matched her silver open-toe Jimmy Choo heels that you can buy at Farfetch and Mytheresa.

These mirrored ankle-strap heels added a few extra inches to the height of the 5’8” actress thanks to their about four-inch heels.
