'Narnia' Child Star Grows Up in the 'Perfect Sisters' Trailer

I don't think we're in Narnia anymore.

The first trailer for the true-crime drama "Perfect Sisters" has debuted here on Yahoo Movies, and it features leading performances by two young actresses making the transistion from child star to grown up leading lady. One, Oscar-nominee Abigail Breslin, has already been establishing an impressive resumé as an adult with roles in last year's "Ender's Game" and "August: Osage County." But her co-star Georgie Henley is taking her first steps out of the wardrobe and into adulthood.

Henley was just 7 years old when she auditioned for the part of Lucy, the youngest of the Pevensie siblings, in the movie adaptation of C.S. Lewis's "The Chronicles of Narnia: The Lion, the Witch and the Wardrobe." The native of England won a Young Artist Award in 2006 for Best Performance in a Feature for her film debut. Henley reprised the role of Lucy two more times for the "Narnia" sequels "Prince Caspian" and "The Voyage of the Dawn Treader," but she took a break from acting professionally after that to focus on school.

For her return to acting, the now 18-year-old Henley chose a role that couldn't be more different from the big-budget fantasy world of her earlier films. "Perfect Sisters" is based on the true story of Canadian siblings Sandra and Beth Andersen, known in the media as the "Bathtub Girls." In 1998, the pair murdered their mother Linda, an alcoholic with a history of abusive boyfriends, by plying her with pills and liquor and then holding her head under water in the tub. In the film, Breslin plays the older sister Sandra, Henley is the younger Beth, and Oscar-winner Mira Sorvino portrays their doomed mother.

Henley started college last fall at Cambridge University, where she continues to act in plays while she studies. She also has another film already in the can, "The Sisterhood of the Night," where she plays an American teen who leads a group of girls into the woods nightly for a mysterious gathering. Odds are, there won't be a talking lion there, either.

"Perfect Sisters" will be released in select cities on April 11.
